Mica is a non-metallic mineral raw material, mainly including biotite, phlogopite, muscovite, lepidolite, sericite, green mica, lepidolite, etc. At present, muscovite is the most widely used in industry, followed by phlogopite. Synthetic mica powder wholesale, muscovite has high dielectric strength, low dielectric loss, arc resistance, corona resistance and other excellent properties; and has the characteristics of acid resistance, alkali resistance, high mechanical strength and easy to peel into pieces. Although the above-mentioned main properties of phlogopite are inferior to that of muscovite, it has higher heat resistance. In particular, there is a light-colored phlogopite called amber mica, which has better properties than muscovite and is a rare kind of phlogopite. Heat resistant insulating material.

Due to these excellent properties of mica, it has a wide range of uses in industry, such as insulating materials for electronic, electrical, telecommunication, electrical, marine, transportation, instrumentation, construction and other industrial products, including capacitors, electron tubes, carrier waves, oscillators high-voltage and high-power generators, motors, DC motors; high-voltage electrical equipment and civil electrical equipment, etc. Mica powder can also be used to make special parts for high pressure boilers, instruments and meters, or special paints and some special fillers for sea ships and ships.

Large pieces of muscovite and phlogopite have long been indispensable and important raw materials in the electrical industry, aerospace and defense industries. But globally, the resources of large mica are extremely limited, and the output is decreasing year by year. Through the study of mineral morphology, researchers have found that natural mica (including sericite) with a scaly structure has many functions similar to that of large pieces of mica, such as insulation, anti-ultraviolet and nuclear radiation, and has a wide source of raw materials, easy processing, and low cost. Therefore, crushed mica and its powder have been widely used.
