Domestic Talc Powder In The Application Of The Top Ten Industries

First, the definition of talcum powder

Talcum powder (pulvistalci) mainly of talc, talc is the main composition is hydrated magnesium silicate, formula for Mg3 (Si4O10) (OH) 2. Talc is a monoclinic system. Crystal show fake six-party or diamond shape, I see. Usually into dense clumps, leaf shape, radial, fibrous assembly. Colorless transparent or white, but because it contains a small amount of impurity in light green, yellow, light even light red; The cleavage plane is pearl luster. 1, hardness, specific gravity 2.7 ~ 2.8.

Second, the characteristics of the talcum powder

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.

Three, the purpose of the talcum powder
