Talc powder introduction

The main component of talc powder is talc. Talcum powder

CAS No. : 14807-96-6

The main component of talc is hydrated magnesium silicate, whose molecular formula is Mg3 [Si4O10] (OH)2. Talc is a monoclinal system. The crystal is a pseudo - hexagonal or diamond - shaped sheet, occasionally seen. It is usually a dense mass, leaf, radial and fibrous aggregate. Colorless transparent or white, but light green, light yellow, light brown or even light red due to a small amount of impurities; The cleavage surface is of pearl luster. Hardness 1, specific gravity 2.7 ~ 2.8.

Talc have lubricity, fire resistance, acid resistance, insulation, high melting point, chemical inertness, good covering power and soft, good luster, strong adsorption force and other excellent physical and chemical properties, due to the crystallization of talc is a layered structure, so the easier to split into flake trends and special lubrication, if the content of Fe2O3 high will reduce its insulation.
