OF super grade, Grade I and II is exported. Fine talcum powder is of high whiteness in very fine granula tion which feels soft and slippery, so it is used in hitech fields, such as paint and coating industry, it is also used in paper making industry. Besides calcine talcum powder from 200 mesh to 1250 mesh is used in china and pottery industry. The following kinds such as Qixia3-grade blocks, 3-grade grains, 4 grade block and 4-grade grains are used as raw materials of china and pottery products. When 15% 80% of talcum powder is added in porcelain ,the Final china products is of very heat expansion, but of high strength, transparency and brilliance in colure and of very high percentage silicon , alg but of very low percentage of iron and aluminium.
