Supply Talc Talc Talc stone industry

Talc Talc is a main component hydrous magnesium silicate, the formula Mg3 [Si4O10] (OH) 2. Talc belong to monoclinic. Crystal was fake six-party or diamond-shaped flakes, occasionally. Usually a dense block, leaf-shaped, radial, fibrous assemblies. Colorless or white, but with a small amount of impurities and showed light green, light yellow, light brown or even light red; cleavage plane was pearl luster. Hardness 1, the proportion of 2.7 to 2.8. Talc has a lubricating, anti-sticking, glidants, fire resistance, acid resistance, insulation resistance, high melting point, chemically inert, hiding good, soft, shiny, strong adsorption of other excellent physical and chemical properties, as talc The crystal structure is layered, so easy to split into scales of trends and special lubricity, if high Fe2O3 content will reduce its insulation.
