Offer EPTlc powEPTuse for Wi-fi electric powered porcelain
EPTlcum Powder is a exclusive natural mineral make by means of verification amp fine grinding. This item could be used in Paints, Beauty, Paper, Pharmaceuticals, FerEPTzers and so forth.
EPTlc lubricity, fireplace resistance, acid resistance, insulation, high melting point, chemical inertness, very good masking EPT and soft, excellent gloss, robust adsorption capacity, superb bodily and chemical houses, the crystal construction of talc is a layer, so it is straightforward to spEPT into flake craze and EPT lubrication and if the Fe2O3 material is extremely higher will decrease its insulation.
The major element of talc is hydrotalcite conXiHu (West Lake) Dis.Hu (West Lake) Dis. magnesium silicate, and the formula is Mg3 [Si4O10] (OH) two. EPTlc beEPTs to monoclinic method. The crystal is bogus, 6 sides or diamond flakes, at times. Normally dense clumps of leaves, rays, and fibrous aggregates. Colorless or white, but with a little volume of impurities and has ligEPT green, ligEPT yellow, ligEPT brown or pale crimson the cleavage airplane is Pearl luster. Hardness 1, certain gravity two.seven ~ 2.eight.
Shade is snow white
Luster is uninteresting to pearly or greasy
Transparency crystals are translucent and masses are opaque
Crystal system is mono-clinic two/m
Hardness is 1.
Distinct Gravity is two.7 – 2.eight
