We are offering tourmaline 【properties and structure of a tourmaline】 tourmaline is a kind of silicate minerals boron-aluminum with boron-containing characterized and aluminum, sodium, iron, lithium cyclic structure. The chemical formula is nar3al6[si6o18](bo3)3(oh)4. Tourmaline's process name is known as "tourmaline (chinese name is "bixi")", gem-quality tourmaline collectively referred to as "tourmaline (bixi)". Because of the colorful, transparent and flawless loved by the people, ranking first in the list of mid-range gems. Tourmaline colors with different components, iron-rich tourmaline is black, rich in lithium, manganese and cesium is rosy or light blue; magnesium-rich tourmaline is often in brown and yellow, chromium- rich is in dark green tourmaline. Tourmaline has a vitreous luster, no cleavage, the hardness is 7.0-7.5 with brittle, the proportion is 3.03-3.25g/cm3, has piezoelectric and pyroelectric properties. The tourmaline crystals is columnar, aggregate is in rod-shaped, radial, small needle-like, also in dense block or implicitly crystalline. Our factory mainly produce iron tourmaline, divided into two kinds of fibrous crystal shape (hexahedral structure) and loose shape. 【 physical and chemical properties of tourmaline】 ingredients al2o3 b2o3 k2o nao2 mgo sio2 fe2o3 cao content (%) 34.98 10.94 0.036 0.91 0.20 34.60 15.80 trace remark 97.466% 【the usage of tourmaline】 tourmaline has unique physical and chemical properties of the piezoelectric and pyroelectric properties, so it has far-infrared band of the electromagnetic radiation to produce negative oxygen ions, as well as anti-bacterial, deodorizing functions. Therefore, in recent years, is widely used in the field of functional fibers, textiles, clothing, coating materials, water purification, building materials, daily necessities, and composite materials. Changes by temperature and pressure to cause the electric potential difference of tourmaline crystals, so that the surrounding air ionization occurs i.e. Negative oxygen ions in the air, so as to achieve the purpose of purifying the air, the polyester fibers can have a far infrared thermal features, deodorant function, negative ion emission function and antibacterial function, called "singular fibers. Tourmaline also used in other fields: 1). High purity tourmaline gem material, made of all kinds of jewelry pendant necklaces, bracelets, etc. 2). Antibacterial deodorant wallpaper, floors, ceilings, furniture, interior paint and concrete. 3). The antimicrobial preservation packaging material, such as plastic film, box and wrapping paper and cardboard boxes, etc.. 4). filter health fillers. 5). Water and air purification materials. 6). Toothpaste, cosmetics and other additives. 7). Antimicrobial coating or a coating material for electronic devices, household appliances, and daily life goods. 8). Having antibacterial, sterilization, deodorization and other functions of the far-infrared radiation composite ceramics.

We are offering hematite. Hematite is a kind of vice mineral which widely distributed in a variety of rock, it is usually as the finely dispersed granular appears in many igneous rock, in special circumstances, it forms huge blocks in the regional metamorphite. In the red sandstone, hematite is the cements of quartz particles and it can color the rock. Hematite is iron oxide, heavy and hard. The iron content of hematite is as high as 70% and it can be putout in a large number, so it is the most important iron ore. The name of hematite is derived from his dark red. There are several forms of hematite, people gave them different names according to their different forms. For example, shiny steel gray crystals called specularite, the scaly called mica hematite, a soft earthy called ocher, many spherical together called renal mine, and fibrous called document iron ore, etc. Hematite are very widespread. It can be generated in many cases, but the main hematite ore deposit is from the deposition. Hematite often to be output together with magnetite. In addition to iron-making, the powdered hematite has also been used as a red pigment and abrasive.
