Quality White Substantial Pure Beauty Quality EPTlc PowEPTfactory
EPTlcum Powder is a distinctive organic mineral make by way of verification amp fine grinding. This solution may possibly be used in Paints, Cosmetic, Paper, Pharmaceuticals, FerEPTzers and so on.
EPTlc lubricity, hearth resistance, acid resistance, insulation, substantial melting stage, chemical inertness, great covering EPT and gentle, very good gloss, robust adsorption ability, exceptional actual physical and chemical houses, the crystal structure of talc is a layer, so it is simple to spEPT into flake development and EPT lubrication and if the Fe2O3 articles is very higher will reduce its insulation.
The principal part 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 program. The crystal is fake, six sides or diamond flakes, from time to time. Generally dense clumps of leaves, rays, and fibrous aggregates. Colorless or white, but with a little amount of impurities and has ligEPT inexperienced, ligEPT yellow, ligEPT brown or pale purple the cleavage aircraft is Pearl luster. Hardness 1, distinct gravity 2.seven ~ two.eight.
Physical 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
Hardness is one.
