矽酸镁
为硅酸镁盐类矿物滑石族滑石，主要成分为含水硅酸镁，经粉碎后，用盐酸处理，水洗，干燥而成。
滑石主要成分是滑石含水的矽酸镁，分子式为mg3［si4o10］( oh)2。滑石属单斜晶系。晶体呈假六方或菱形的片状，偶见。通常成致密的块状、叶片状、放射状、纤维状集合体。无色透明或白色，但因含少量的杂质而呈现浅绿、浅黄、浅棕甚至浅红色；解理面上呈珍珠光泽。硬度1，比重2.7～2.8。
滑石具有润滑性、抗黏、助流、耐火性、抗酸性、绝缘性、熔点高、化学性不活泼、遮盖力良好、柔软、光泽好、吸附力强等优良的物理、化学特性，由于滑石的结晶构造是呈层状的，所以具有易分裂成鳞片的趋向和特殊的滑润性，如果fe2o3的含量很高则会减低它的绝缘性。

magnesium silicate
1. the overview.
magnesium silicate
is the main component of talc. english name: talc
cas no. : 14807-96-6
magnesium silicate
molecular weight: 260.8617
magnesium silicate
chinese alias: hydrated magnesium silicate superfine powder
magnesium silicate
molecular structure, molecular structure
magnesium silicate
for magnesium salt mineral silicate talc talc, main ingredient is hydrated magnesium silicate, after crushing, treated with hydrochloric acid, water washing and drying.
talc is the main ingredient is hydrated magnesium silicate, formula for mg3 [si4o10] (oh) 2. talc is a monoclinic system. crystal show fake six-party or diamond shape, i see. usually into dense clumps, lamellar, radial, fibrous assembly. colorless transparent or white, but because it contains small amounts of impurities in light green, yellow, jianzong even pale red; the cleavage plane is pearl luster. 1, hardness, specific gravity 2.7 ~ 2.8.
talc lubricity, sticky, flow resistance, fire resistance, acid resistance, insulation, high melting point, chemical inertness, good hiding power, good soft, gloss, strong adsorption capacity, such as excellent physical and chemical properties, due to the crystallization of talc is a layered structure, so it is easy to split into flake trend and special lubrication, if fe2o3 content high will reduce its insulation.
2. the magnesium silicate
purpose:
(1) cosmetic grade magnesium silicate
(hz) : used for various skin powder, cosmetic powder, talcum powder, etc.
(2) medical - food grade magnesium silicate
