Wancheng Dehydrated mica

Dehydrated mica is mica produced by roasting natural mica at high temperature, and 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 display a color system with yellow and red as the main colors after calcination, and natural biotite will generally display a golden color after calcination. 

Dehydrated mica, because its water content is about 10 times lower than ordinary mica, has produced many special properties and is widely used in many fields. The industry mainly uses its high electrical insulation and heat resistance, as well as strong aci d resistance, alkali resistance, pressure resistance and stripping performance, as insulation materials for electrical equipment and electrical equipment. Mainly used in electrical, national defense, building materials, fire fighting, fire extinguishing agents, welding electrodes, plastics, electrical insulation, papermaking, asphalt paper, rubber, pearlescent pigments and other fields.
