We are offering calcite powder. Calcium carbonate, or caco3, is one of the most useful and versatile materials known to man. it is extremely common and found throughout the world in sedimentary, metamorphic and igneous rocks. Some geologists consider it to be a ubiquitous mineral one that is found everywhere. It comprises more than 4% of the earths crust and is found throughout the world. Its most common natural forms are chalk, limestone, and marble, produced by the sedimentation of the shells of small fossilized snails, shellfish, and coral over millions of years. Although all three forms are identical in chemical terms, they differ in many other respects, including purity, whiteness, thickness and homogeneity. The properties of calcite make it one of the most widely used minerals. It is used as a construction material, abrasive, agricultural soil treatment, construction aggregate, pigment, pharmaceutical, acid neutralization, sorbents, monuments & statuary and more. It has more uses than almost any other mineral. Calcite has a hardness of 3.0 on the mohs scale and that makes it suitable as a low-hardness abrasive.Calcium carbonate as chalk has been used as a writing tool for over 10, 000 years and is a fine, microcrystalline material. As limestone, calcium carbonate is a biogenic rock, and is more compacted than chalk. As marble, calcium carbonate is a coarse-crystalline, metamorphic rock, which is formed when chalk or limestone is re-crystallized under conditions of high temperature and pressure.

We are offering dolomite powder. Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of camg(co3)2. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble. Limestone that contains some dolomite is known as dolomitic limestone. Dolomite is rarely found in modern sedimentary environments but dolostones are very common in the rock record. They can be geographically extensive and hundreds to thousands of feet thick. Most rocks that are rich in dolomite were originally deposited as calcium carbonate muds that were post-depositionally altered by magnesium-rich pore water to form dolomite. Dolomite has a mohs hardness of 3 12 to 4 and is sometimes found in rhombohedral crystals with curved faces. Dolomite produces a very weak reaction to cold, dilute hydrochloric acid; however, if the acid is warm or if the dolomite is powdered a much stronger acid reaction will be observed. (powdered dolomite can easily be produced by scratching it on a streak plate.).Dolomite is very similar to the mineral calcite. Calcite is composed of calcium carbonate (caco3) while dolomite is a calcium magnesium carbonate (camg(co3)2). These two minerals are one of the most common pairs to present a mineral identification challenge in the field or classroom. The best way to tell these minerals apart is to consider their hardness and acid reaction. Calcite has a hardness of 3 while dolomite is slightly harder at 3 12 to 4. Calcite is also strongly reactive with cold hydrochloric acid, while dolomite will effervesce weakly with cold hydrochloric acid.
