Mica gasket is made by cuting or rushing mica sheet. The mica sheet is made by heating suppresssing. combining the 90% mica and 10% glue.
Mica is straliform mineralits composed of potassium (K), aluminum(Al). magnesium
(Mg),. lron(Fe) and ithium(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 alkai resistant, and corrosion proof, which can be stripped, with low coefficient of expansion etc.
