云母片由多硅白云母、石英、石榴石和金红石等组成，可出现钠长石、黝帘石及硬绿泥石等，石榴石富Fe和Mg，多硅白云母中的Si可达3.369，也是高压组合。有绝缘及低损失的热阻功能，还是很好的黑体。
Thick piece of natural mica is mica through peeling points and thickness, cutting, drilling or stamping system formed, with a certain thickness, some form of mica parts, the product is suitable for TV sets, power capacitors, thermal relay, surveillance display, aerospace, aviation, communications, radar, heat-resistant matrix tablets such as raw materials. Sub: electric heater chip heater protection films, gaskets, tubes, sheets, lamp film, its material as a natural mineral products, with no pollution, insulation resistance, good voltage performance characteristics, according to customer demand for punching all kinds of natural mica.
Types of mica: mica - muscovite film - Gold Mica - Black Mica - sericite films - lithium mica - sodium mica - vanadium mica - mica debris - large mica
By use of mica flakes of mica are generally divided into the (thin mica), mica capacitors, and electronic tubes Mica thick slices into three categories, three categories of mica in the area and thickness specifications, respectively, and the level and use the following form.
Widely used in electrical products mica and their products as insulating material. The varieties are: natural mica, synthetic mica, mica tape, mica plate, mica foil, mica and glass.
More types of mica, used as electrical insulation materials have two kinds of muscovite and phlogopite. Muscovite has a glass sheen, generally colorless and transparent; gold mica metallic gloss and semi-metallic luster, often with golden yellow, brown, light green, etc., poor transparency. Muscovite and phlogopite have good electrical and mechanical properties, good heat resistance, chemical stability and good resistance to corona. Two kinds of mica can be processed into strip thickness from 0.01 to 0.03 mm of soft and flexible sheet. The electrical properties of muscovite mica better than gold, but gold mica soft, good heat resistance than muscovite.
