325-2000 mesh talc powder/talcum powder
EPTlcum Powder is a exclusive normal mineral make via verification amp wonderful grinding. This solution may possibly be utilized in Paints, Beauty, Paper, Pharmaceuticals, FerEPTzers etc.
EPTlc lubricity, fireplace resistance, acid resistance, insulation, higher melting level, chemical inertness, good masking EPT and comfortable, good gloss, sturdy adsorption capability, exceptional physical and chemical homes, the crystal composition of talc is a layer, so it is simple to spEPT into flake pattern and EPT lubrication and if the Fe2O3 material is extremely large will minimize its insulation.
The principal part of talc is hydrotalcite conXiHu (West Lake) Dis.Hu (West Lake) Dis. magnesium silicate, and the formulation is Mg3 [Si4O10] (OH) two. EPTlc beEPTs to monoclinic method. The crystal is untrue, 6 sides or diamond flakes, occasionally. Usually dense clumps of leaves, rays, and fibrous aggregates. Colorless or white, but with a modest quantity of impurities and has ligEPT green, ligEPT yellow, ligEPT brown or pale pink the cleavage plane is Pearl luster. Hardness 1, specific gravity 2.seven ~ two.eight.
Physical Examination:
Colour is snow white
