Mica Products Industry Overview: Multi-scenario Core Material with Bright Prospects
Mica is a group of layered aluminosilicate minerals. Boasting excellent insulation, high temperature resistance, chemical stability, flame retardancy and corrosion resistance, it is processed into an indispensable functional material for modern industry. It is widely applied in new energy, power, home appliances, rail transit, high-temperature smelting and other fields, with steadily expanding industry scale and growing application scope.
Core Properties and Classification of Natural Mica
Mica is a layered aluminosilicate mineral with platy crystal structure. It features superior electrical insulation, high temperature resistance, chemical stability, flame retardancy, corrosion resistance and good flexibility, making it an ideal raw material for manufacturing high-end insulating, thermal insulation and flame-retardant materials.
Muscovite
Amber-hued with pearly luster and high transparency. It delivers superior electrical insulation and thermal stability, and is a mainstream material for electrical insulation applications.
Phlogopite
Features greasy luster and semi-transparency. It has exceptional high-temperature resistance, suitable for service under high-temperature working conditions.
Synthetic Mica
Bright pearly appearance, high purity and transparency with stable and consistent properties, meeting the requirements of high-end precision applications.
Calcined Mica
Possesses pearly luster with a slight reddish-brown tint and good transparency. High-temperature treatment further enhances its stability and heat resistance.
