Pharmaceutical quality talc powEPTfor filler Very best high quality
EPTlcum Powder is a special natural mineral generate by way of verification amp fantastic grinding. This solution could be used in Paints, Cosmetic, Paper, Prescription drugs, FerEPTzers etc.
EPTlc lubricity, fire resistance, acid resistance, insulation, substantial melting stage, chemical inertness, very good covering EPT and soft, very good gloss, powerful adsorption ability, exceptional actual physical and chemical houses, the crystal structure of talc is a layer, so it is straightforward to spEPT into flake trend and EPT lubrication and if the Fe2O3 articles is very high will minimize its insulation.
The primary element of talc is hydrotalcite conXiHu (West Lake) Dis.Hu (West Lake) Dis. magnesium silicate, and the formula is Mg3 [Si4O10] (OH) 2. EPTlc beEPTs to monoclinic program. The crystal is bogus, six sides or diamond flakes, at times. Normally dense clumps of leaves, rays, and fibrous aggregates. Colorless or white, but with a tiny sum of impurities and has ligEPT inexperienced, ligEPT yellow, ligEPT brown or pale purple the cleavage plane is Pearl luster. Hardness one, certain gravity two.7 ~ 2.eight.
Physical Evaluation:
Colour is snow white
Luster is boring to pearly or greasy
Transparency crystals are translucent and masses are opaque
Crystal program is mono-clinic 2/m
Hardness is 1.
Particular Gravity is two.seven – two.eight
