Pyrophyllite is Aluminum Silicate Hydroxide or called gibbsite layer which crystalline structure is 2:1，belongs to clay mineral. Its Chemical structure is Al2 [Si4O10(OH)2。Pyrophyllite has a fine texture, and its hardness is low (1-2). The company's newly developed pyrophyllite mining reserves reach to 200 million tons. With Al reached 16%~30%, Fe2O3+Ti2O <0.2%. Suitable for the use of synthetic diamond Blank (mold), ceramics, refractory, glass fiber, stone carving. It can be widely used in ceramics, metallurgy, building materials, chemical industry, light industry and other industrial sectors.
1，Suitable for the use of synthetic diamond Blank (mold)。The diamond with production of pyrophyllite has good quality, pure color, and has no bubbles, well crystal, transparent and fewer impurities, no black particles. The economic benefits have increased significantly. It is a popular material in the diamond-producing.
2，Ceramics. Pyrophyllite has a small linear expansion coefficient. there is a certain linear expansion before the sintering temperature range (1050--1150 ° C). Such linear expansion can offset the contraction during the process of firing caused by other materials, thereby slacken the firing range and, Can guarantee the size of the products. Pyrophyllite has good thermal stability with low expansion; thus can be used to create good products with accurate size and Thermal Stability. In addition, pyrophyllite produced by our company has another great feature of high in calcium and magnesium containing the embryo to add appropriate materials Glaze (5%----10%). and the elimination of bubbles can also pinhole, in order to ensure the formation of smooth glazed embryos, but also has good mud flows, permeability, drying shrinkage small embryo, resistance to deformation, crack resistance, high brightness, its results were better than other similar products against degeneration, which can be widely used in sanitary ware, tiles, glazed tiles, tile, household ceramics, and cosmetics into soil and thin glaze pottery. 3，Refractory. Pyrophyllite can be made refractory clay slurry, the refractory coatings, fire-resistant concrete aggregate, manufacturing crucible casting dope with clay. Which Refractoriness can reach to 1700 ℃.
