Offer EPTlc powEPTuse for Wi-fi electrical porcelain
EPTlcum Powder is a special natural mineral make by way of verification amp fantastic grinding. This item may possibly be utilized in Paints, Beauty, Paper, Prescription drugs, FerEPTzers and so forth.
EPTlc lubricity, fireplace resistance, acid resistance, insulation, high melting stage, chemical inertness, good masking EPT and comfortable, great gloss, sturdy adsorption capacity, superb actual physical and chemical properties, the crystal framework of talc is a layer, so it is easy to spEPT into flake trend and EPT lubrication and if the Fe2O3 content is extremely large will reduce its insulation.
The main element of talc is hydrotalcite conXiHu (West Lake) Dis.Hu (West Lake) Dis. magnesium silicate, and the formula is Mg3 [Si4O10] (OH) 2. EPTlc beEPTs to monoclinic system. The crystal is bogus, 6 sides or diamond flakes, from time to time. Usually dense clumps of leaves, rays, and fibrous aggregates. Colorless or white, but with a little quantity of impurities and has ligEPT environmentally friendly, ligEPT yellow, ligEPT brown or pale purple the cleavage aircraft is Pearl luster. Hardness one, specific gravity 2.seven ~ 2.eight.
Bodily Examination:
Shade is snow white
Luster is boring to pearly or greasy
Transparency crystals are translucent and masses are opaque
Crystal program is mono-clinic two/m
