Market research shows that the natural mica sheet is a mica part with certain thickness and shape, which is made of thick mica through peeling, thickness fixing, cutting, drilling or punching. The product is suitable for TV, power capacitor, thermal relay, monitoring display, aerospace, aviation, communication, radar, heat-resistant frame sheet and other raw and auxiliary materials.

　　Mica chip is divided into electric heater chip, electric heater protector, gasket, electronic segment and light bulb. Because its material is natural mineral products, it has the characteristics of pollution-free, insulation and good voltage resistance. It can cut various specifications of natural mica chip according to the needs of customers.

　　Mica and its products are widely used as insulating materials in electrical products. Its varieties are: natural mica, synthetic mica, mica tape, mica plate, mica foil, mica glass, etc

　　There are many kinds of natural mica. There are muscovite and phlogopite as electrical insulating materials. Muscovite has glassy luster, generally colorless and transparent; phlogopite has metallic luster and semi metallic luster, and the common ones are golden yellow, brown, light green, etc., with poor transparency. Muscovite and phlogopite have good electrical and mechanical properties, good heat resistance, chemical stability and corona resistance. Both types of mica can be peeled and processed into soft and elastic flakes with a thickness of 0.01 to 0.03 mm. The electrical properties of Muscovite are better than that of phlogopite, but the phlogopite is soft and the heat resistance is better than muscovite.

　　According to the application, mica can be generally divided into three types: mica flake (flake mica), mica for capacitor and mica thick flake for electron tube. See the following table and its grade and application for the area and thickness specifications of these three types of mica

　　In addition, the use of mica in high school biology: blocking the passage of growth hormone, allowing water to pass through. Control variable, make variable single, verify the effect of growth hormone on plant growth

　　Moreover, in the microwave oven, the function of mica is to allow the microwave to enter the microwave oven and block the emission head of the microwave which is polluted by smoke and so on. Once the emission head is polluted, it will definitely reduce the efficiency of the microwave oven.
