Magnesium silicate molecular structure diagram: molecular structure
The silicate powder is a magnesium silicate mineral talc, the main component of which is hydrated magnesium silicate, after being crushed, treated with hydrochloric acid, washed and dried.
Talc is the main component of talc containing magnesium silicate, molecular formula for Mg3 (Si4O10) 2. Talc is in the form of a single crystal. Crystal is six square or diamond shape, I see. Usually into a dense block, blade like, radial, fibrous aggregate. Colorless or white, but with a small amount of impurities and has light green, light yellow, light brown or pale red; the cleavage plane is Pearl luster. Hardness 1, specific gravity of 2.7 ~ 2.8.
Talc lubricity, anti adhesion, flow aid, fire resistance, acid resistance, insulation, high melting point, chemical inertness, good covering power and soft, good gloss, strong adsorption capacity, excellent physical and chemical properties, the crystal structure of talc is a layer, so it is easy to split into scales the trend and special lubrication, if the Fe2O3 content is very high will reduce its insulation.
