Clients can avail excellent quality Pyrophyllite Lumps from us. Pyrophyllite is a phyllosilicate mineral species belonging to the clay family and composed of aluminum silicate hydroxide: AlSi₂O₅OH. Pyrophyllite Lumps occur in two more or less distinct varieties, namely, as crystalline folia and as compact masses; distinct crystals are not known. The folia have a pronounced pearly luster, owing to the presence of a perfect cleavage parallel to their surfaces: they are flexible but not elastic, and are usually arranged radially in fan-like or spherical groups. This variety, when heated before the blowpipe, exfoliates and swells up to many times its original volume, hence the name pyrophyllite, from the Greek pyros (fire) and phyllos (a leaf), given by R. Hermann in 1829. The color of both varieties is white, pale green, greyish or yellowish; they are very soft (hardness of 1 to 1.5) and are greasy to the touch. The specific gravity is 2.65 - 2.85. The two varieties are thus very similar to talc. The compact varieties of Pyrophyllite Lumps are used for slate pencils and tailors chalk (French chalk) and carved by the Chinese into different kinds of small images and ornaments. Other soft compact minerals (steatite and pinite) used for these Chinese carvings are included with pyrophyllite under the terms agalmatolite and pagodite. Pyrophyllite occurs in phyllite and schistose rocks, often associated with kyanite, of which it is an alteration product. Pale green foliated masses, very like talc in appearance, are found at Beresovsk near Yekaterinburg in the Urals, and at Zermatt in Switzerland. The most extensive deposits are in the Deep River region of North Carolina, where the compact variety is mined, and in South Carolinaand Georgia. Major deposits of pyrophyllite occur within region of Ottosdal, South Africa, where it is mined for the production of a variety of manufactured goods and blocks are quarried and marketed as "Wonderstone" for the carving of sculptures. In Australia, pyrophyllite has been mined at three sites near Pambula on the Sapphire Coast of NSW. Uses Of Pyrophyllite Pyrophyllite Lumps are easily machined and have excellent thermal stability. Therefore, Pyrophyllite Lumps are added to clay to reduce thermal expansion when firing but they also have many other industry uses when combined with other compounds, such as in insecticide and for making bricks. Pyrophyllite is also widely used in high-pressure experiments, both as a gasket material and as a pressure-transmitting medium. Download

Barytes Powder, also called barite, is a mineral available worldwide, composed of barium sulfate (BaSO₄). The largest deposits are in the U.S., Mexico, China, India and Morocco. The name barytes is derived from the Greek baryas meaning heavy or heavy spar, because its most striking feature is its heaviness. The specific gravity, or weight per unit volume, is 4 to 5, which is about twice that of most common industrial minerals. For comparison, calcium carbonate or limestone has a specific gravity of 2.7. Because of this high density, a teaspoon of barytes would weigh close to the same as a tablespoon of salt, which equals three teaspoons. Barytes Powder can occur in numerous colors; white, brown, yellow, red and gray are most common. The colors are the result of impurities such as iron, strontium and lead, and mineral contaminants such as clay and sand. Barite is insoluble in water and is resistant to acid attack. Uses of Barytes PowderThe largest application of Barytes Powder is as a weighting agent in natural gas and oil field drilling muds. The density of Barytes Powder helps in down-hole flow and bit lubrication. One of its industrial end uses is as a weighting agent additive in cement, rubber and urethane foams. Barytes Powder is used in paint and powder coatings for metal protection and processing improvement. Barytes Powder is also used in friction products such as brake pads and clutch surfaces. Because barite is so dense that it reduces the passage of x-rays it is used in cement vessels for radioactive material containment, in gastrointestinal x-ray milkshakes and in cathode ray masks in television sets and computer monitors. It also absorbs sound, so is included in sound-deadening sealants and underbody coatings in automobile and other vehicle manufacture. Barytes ProductsBarite ore is ground to a range of products of the different sizes needed for the variety of applications. Most commercially available products are 200 or 325 mesh, or finer, down to a few microns. The ore is selected and the process is controlled for one or more of the following properties: color, particle size, specific gravity and bulk density. Some barytes is available in a bleached form to improve color, and there is a precipitated barium sulfate, referred to as blanc fixe, that finds use in high-end paints and coatings and in pharmaceutical applications.

Calcite Powder or Limestone is a common sedimentary rock composed primarily of the calcium carbonate mineral, calcite (CaCO₃). Calcite Powder constitutes approximately 10 percent of the sedimentary rocks exposed on the earth's surface. Calcite Powder is formed either by direct crystallization from water (usually seawater), or by the accumulation of sea animal shells and shell fragments. In the direct crystallization case calcium ions in the seawater combine with atmospheric or dissolved carbon dioxide to form calcium carbonate, which being insoluble, precipitates out. Over time, layers of the calcium carbonate form, and with sufficient time and pressure from overlying materials, are transformed to solid rock. The chemical composition of seawater and its minerals contaminants will be recorded in the limestone impurities. Limestone frequently also contains the minerals dolomite or calcium magnesium carbonate (CaMg(CO₃)₂, and a second crystalline form of calcium carbonate, aragonite. In the seas that covered much of the earth in earlier geological times lived many clams and other shelled forms of animal life. When the animals died, their shells, which are composed of calcium carbonate, fell to the bottom. Thick layers, which can be a mile or 2 kilometers deep, gradually were changed into rock. If the shells were only compressed, with little crystallization occurring, soft chalk results. The White Cliffs of Dover in England are made of this type of chalk. With more time and pressure, a coarsely crystallized rock can form, which is limestone. In limestone, most traces of the animal shells have disappeared. Pure calcite, dolomite, and aragonite, which are in the limestone, are clear or white. However, with impurities, they can take on a variety of colors, commonly white, tan or gray. Limestone can also have gone through metamorphosis, with high pressure, heat and time creating marble. This process tends to intensify the color of the stone as well as changing the nature of some of the impurities. Metamorphosis creates the beautiful marbles seen in architectural applications. Uses of Calcite PowderCalcite Powder and marble are important building materials in most parts of the world. They are used as cut dimension stone (blocks and slabs) for building. In the form of coarsely crushed stone or aggregate limestone is used for general building purposes, roadbeds and as a component in concrete. When heated, the calcium carbonate in limestone decomposes to lime, or calcium oxide, which also has many industrial applications, including the manufacture of precipitated calcium carbonate (PCC). Either limestone or marble may be used as the basis for crushed or ground calcium carbonate. Ground calcium carbonate, commonly referred to as GCC, is very widely used as an industrial mineral. Three primary attributes: particle size, color and chemical purity define the quality of the GCC, and define the suitability of use for any given application. Ground limestone is available in a broad range of sizes. When specifying the size of a ground calcium carbonate, either the top size (the size of the largest particles) or the median particle size (essentially the average) can be used. Commercially, top size is generally specified for coarser industrial minerals, which may be as big as beach sand, which is 10 mesh or 2 millimeters or approximately 0.1 inch in size, or as fine as flour; which is 200 mesh, or 75 microns. Finely ground calcium carbonates can range down in particle size to just a few microns, 1 to 3, with the top size controlled for high performance applications to as fine as 5 to 10 microns. Limestone color can range from brilliant white to light gray and chemical purity can range from only 80-90% calcium carbonate to well over 99.9% purity. Calcium carbonate is not a particularly hard mineral, with pure calcite falling at about 3 on the Mohs scale of 1 (talc) to 10 (diamond). Silica impurities in the limestone can raise the hardness of some ground calcium carbonates to a Mohs value of 4. Calcium carbonate is subject to attack by acidic environments, which has led to the damage of limestone buildings and monuments by acid rain. For industrial uses, the effect of an acid can be somewhat reduced by treating the ground limestone powder with fatty acids to put a non-polar, organic material on the surface. Few industrial minerals can match GCC for its combination of properties and cost. Industrial Applications Calcite Powder In Plastic IndustryGround calcium carbonate or Calcite Powder is cost-effective functional filler for plastics. Besides reducing formulation costs, calcium carbonate provides opacity and surface gloss. Impact strength and flexural modulus are improved when the particle size is carefully controlled to a fine median particle size and a minimum top size. Further improvement in impact strength and flexural modulus is possible with the appropriate surface treatment on the fine ground calcium carbonate. The surface treatment also enhances the dispersion of the filler in the resin system. Calcite Powder can be incorporated into a number of resin systems including, but not limited to rigid and flexible polyvinyl chloride, polyethylene, polypropylene, unsaturated polyesters, polyester, polyurethane, nylon, and polyacrylate. Within these systems, the Calcite Powder has the following functionalities :

• Impact modifier, filler and opacifier in PE compounds
• Impact modifier, filler and opacifier in PP compounds
• Reinforcing filler for HDPE
• Filler in flexible PVC wire and cable coverings
• Promoter of gas and vapor permeability in breathable LLDPE film
• Antiblock in low clarity LLDPE film
• Impact modifier and filler in rigid PVC potable water pipe
• Impact modifier and filler in rigid PVC general purpose pipe
• Shrinkage control, mechanical property enhancement in SMC/BMC, unsaturated polyester compounds
• Resin extender for Polyolefins, PVC and engineering resins
• Reinforcing filler for nylon

Surface treated ground calcium carbonate products disperse easier in most polymeric systems when compared to untreated products. The typical surface treatment is stearic acid. Calcite Powder In Paints and CoatingCalcite Powder or Ground calcium carbonate (GCC)âalso called ground limestone, whiting, or chalkâis the most widely used extender mineral in coatings applications. It is available worldwide and close to most paint manufacturing locations. It is very bright and comes in a wide range of particle size distributions. Finally, it is the most economical of all common filler minerals. The widest use for GCC is as filler in architectural or decorative coatings. While it is primarily used in interior paints, it is included in some exterior formulations as well. It tends to be the filler of choice for paints sold at a low price point and/or where longevity is not the primary attribute. That said, GCC is also used in top-of-the-line flat or matte finishes. High-brightness calcium carbonates are selected for ceiling paints and other applications requiring high dry hiding and are formulated above the critical pigment volume concentration (CPVC). By combining two or more grades of different particle sizes, thus altering the particle size distribution of the filler package; manufacturers can adjust the flatness of finish of interior architectural coatings and improve the scrubability of the final paint film. GCC can be used in exterior building paints as long as the pigment volume concentration (PVC) is not too high. The PVC must be sufficiently low with enough binder present so that the film does not become too porous over time. GCCs are also economical extenders included in road-marking and traffic-paint formulations to lower costs while still meeting the optical specifications for the finished film. Although GCCs have many desirable traits, it is not a universal extender mineral. It will react with acids, so its use it limited to areas where it will not be exposed to acid rain or other acidic fumes or liquids. In contrast to high-aspect ratio platy talcs, calcium carbonates, with their round or nodular particle shape and low aspect ratio, make relatively little contribution to improved film formation and integrity and will increase film porosity. For these reasons, the use of GCCs is limited in industrial, marine, and metal-protective maintenance coatings.

We are one of the leading firms actively involved in bringing forth the finest quality Dolomite Powder. Dolomite was named for the French mineralogist Deodat de Dolomieu. The mineral dolomite is commonly found in deposits of a sedimentary rock called dolostone. There are two types of materials often called dolomite, a true chemically uniform calcium magnesium carbonate with the chemical formula CaMg(CO₃)₂, and a dolomitic limestone, which is just an irregular mixture of calcium and magnesium carbonates. Dolomite is believed to have formed by replacement of some of the calcium in a calcium carbonate limestone deposit with magnesium, while the sediment was undergoing lithification, being converted from layers of dead clam and other sea animal shells into crystallized calcite or calcium carbonate. The resultant dolomite mineral, CaMg (CO₃)₂ is a true double salt. The calcium and magnesium ions in dolomite exist in separate layers in the crystal matrix. Dolomite has a calcium layer, then a carbonate layer, then a magnesium layer then a carbonate layer, and so on. Dolomite is harder and denser than the calcite form of calcium carbonate or limestone, and is more chemically inert and more impervious to acid attack. Uses Of Dolomite PowderThe inherent differences between Dolomite Powder and calcite drive the applications for dolomite. Dolomite Powder is chosen for many construction and building product applications due to its increased hardness and density. Asphalt and concrete applications prefer dolomite as filler for its higher strength and hardness. Dolomite also finds use in a number of applications as a source of magnesium such as glass and ceramics manufacture, as well as a sintering agent in iron ore pelletization and as a flux agent in steel making. Farmers use dolomite for agricultural PH control. The chemical industry uses the mineral dolomite in making magnesium salts including magnesia, magnesium oxide (MgO), which is used in pharmaceuticals. As an industrial mineral, between Dolomite Powder's usage is significantly less than calcites. This is primarily due to the relative lack of high brightness deposits of dolomite. The alteration process that forms dolomite tends to bring in additional impurities that reduce brightness or tint the stone brown or gray. In regions where high brightness dolomites do exist, they share many of the applications of calcium carbonate.
