General Introduction of ?raw black mica ?cutting:?
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.
