Mica sheets are composed of polysilicon muscovite, quartz, garnet and rutile, etc. Albite, zoisite and chlorite can appear, garnet is rich in Fe and Mg, and Si in polysilicon muscovite can reach 3.369. Also a high pressure combination. It has thermal resistance function of insulation and low loss, and it is also a good black body.
What is mica sheet
Natural mica sheet is made of thick mica after peeling, thickness setting, cutting, drilling or punching. It has a certain thickness and a certain shape. , aerospace, aviation, communication, radar, heat-resistant skeleton sheet, etc. It has the characteristics of good insulation and voltage resistance, and various specifications of natural mica sheets can be punched out according to customer needs.
Classification of mica flakes
There are many kinds of natural mica, and there are two kinds of muscovite and phlogopite used as electrical insulation materials. Muscovite has glass luster, generally colorless and transparent; phlogopite has metallic luster and semi-metallic luster, common ones are golden yellow, brown, light green, etc., and the transparency is poor. Muscovite and phlogopite have good electrical and mechanical properties, good heat resistance, chemical stability and corona resistance. Both types of mica can be exfoliated and processed into soft and elastic flakes with a thickness of 0.01 to 0.03 mm. Muscovite has better electrical properties than phlogopite, but phlogopite is softer and has better heat resistance than muscovite.
According to the application, mica can be generally divided into three categories: mica flakes (thin flake mica), mica for capacitors and mica thick flakes for electron tubes.
Use of mica sheet
Mica and its products are widely used as insulating materials in electrical products. Its varieties include: natural mica, synthetic mica, mica tape, mica board, mica foil, mica glass, etc.
