Good quality White Large Pure Beauty Grade EPTlc PowEPTfactory
EPTlcum Powder is a distinctive all-natural mineral generate via verification amp fantastic grinding. This solution may possibly be used in Paints, Beauty, Paper, Pharmaceuticals, FerEPTzers and so forth.
EPTlc lubricity, hearth resistance, acid resistance, insulation, large melting position, chemical inertness, very good masking EPT and soft, great gloss, powerful adsorption ability, superb physical and chemical homes, the crystal structure of talc is a layer, so it is straightforward to spEPT into flake trend and EPT lubrication and if the Fe2O3 content is extremely large will minimize its insulation.
The major element of talc is hydrotalcite conXiHu (West Lake) Dis.Hu (West Lake) Dis. magnesium silicate, and the method is Mg3 [Si4O10] (OH) two. EPTlc beEPTs to monoclinic technique. The crystal is false, 6 sides or diamond flakes, from time to time. Normally dense clumps of leaves, rays, and fibrous aggregates. Colorless or white, but with a modest amount of impurities and has ligEPT inexperienced, ligEPT yellow, ligEPT brown or pale crimson the cleavage airplane is Pearl luster. Hardness 1, particular gravity 2.seven ~ two.eight.
Bodily Examination:
