Talc is a common silicate mineral that is very soft and has a slippery feel. It is the softest mineral known, with a hardness of 1 on the Mohs scale. Talc has excellent physical and chemical properties such as lubricity, anti-adhesion, flow aid, fire resistance, acid resistance, insulation, high melting point, chemical inactivity, good covering power, softness, good gloss, and strong adsorption. Talc crystals The structure belongs to the monoclinic system, which is composed of magnesium and silicon in hot water solution and rocks. It is distributed in Liaoning, Shanxi, Shaanxi, Shandong, Jiangsu, Zhejiang, Jiangxi and other places, and has abundant reserves.
