Muscovite mica powder and flakes
1. Product name : Mica
Mica is stratiform mineral ,Its composed of potassium (K), aluminum (AI),magnesium (Mg),Iron(Fe) and
lithium(Li).There are different categories of mica, including white mica, phlogopite, biotite and lepidolite
(Lithia mica) . white mica is widely used in industry and national defense because it is elasticity, tenacity
and insulativity. it is also acid and alkali resistant, and corrosionproof, which can be stripped, with low
coefficient of expansion etc.
