Quality White Higher Pure Cosmetic Grade EPTlc PowEPTfactory
EPTlcum Powder is a exclusive normal mineral generate by means of verification amp fantastic grinding. This merchandise may possibly be utilised in Paints, Beauty, Paper, Pharmaceuticals, FerEPTzers and so on.
EPTlc lubricity, hearth resistance, acid resistance, insulation, substantial melting point, chemical inertness, good masking EPT and gentle, very good gloss, sturdy adsorption ability, excellent physical and chemical houses, the crystal structure of talc is a layer, so it is straightforward to spEPT into flake craze and EPT lubrication and if the Fe2O3 material is extremely substantial will minimize its insulation.
The main 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 fake, six sides or diamond flakes, sometimes. 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 red the cleavage plane is Pearl luster. Hardness 1, distinct gravity two.7 ~ two.eight.
Actual physical Evaluation:
Colour is snow white
Luster is boring to pearly or greasy
Transparency crystals are translucent and masses are opaque
Crystal technique is mono-clinic 2/m
