General Introduction of sericite mica  powder

1.Mica is a kind of rock-forming minerals. Its form is platelike or flaky.the colour is variable with the differences of   chemical composition. Mainly Fe content increase will make the colour be darker.

2. the characteristics of mica contains: insulation,high temperature resistant,lustrous appearance, stable physical and chemical property,good heat insulation, excellent elasticity and high toughness etc. 

 

Particle Size of sericite mica powder

   It contains  3-5mm,1-3mm,15mesh,20mesh,40mesh,60mesh,80mesh,100mesh,200mesh,325 mesh,400 mesh etc.
