Calcined mica (Dehydrated mica)
Dehydrated mica is the mica produced by calcining natural mica at high temperature, which is also called calcined mica.
Natural mica of various colors can be dehydrated, and its physical and chemical properties have changed greatly. The most intuitive change is the change of color. For example, natural white mica will show a color system dominated by yellow and red after calcination, and natural biotite will generally show a golden color after calcination.
