Unique Properties Product Description The main component of talc is magnesium silicate with water content of talc, and its molecular formula is Mg3[Si4O10](OH)2. Talc belongs to monoclinic system. The crystal is pseudohexagonal or rhombic, occasionally seen. They are usually compact, massive, leaflike, radial and fibrous aggregates. It is colorless, transparent or white, but it is light green, yellow, brown or even light red due to a small amount of impurities; the cleavage sur...
