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 surface is pearl luster. Hardness 1, specific gravity 2.7-2.8.

Characteristic
Talcum powder has excellent physical and chemical properties, such as lubricity, fire resistance, acid resistance, insulation, high melting point, chemical inactivity, good covering power, softness, good luster, strong adsorption, etc. because the crystal structure of talc is layered, it has the tendency to split into scales and special lubricity.
