Product Details

Fluorophlogopite mica (also known as artificial mica, synthetic mica large crystal), belongs to the silicate artificial mica crystal, is in the high temperature state of 1500 ℃, through strict process conditions and material ratio, in the platinum crucible smelting mica single crystal. Its chemical formula is KMg3(AlSi3O10)F2;

Because the Fluorophlogopite mica is grown under strict process conditions and material ratio (otherwise mica crystals cannot be generated), its texture is very pure and its electrical properties are very good. The volume resistivity is 1015~1016 Ω · cm (about 1000 times higher than that of natural mica); the electric breakdown strength is 185~238 kV/mm, which is 10 times that of PTFE; it can work at 1100 ℃ for a long time. The melting and crystallization temperature is 1375 degrees C. The stability of hot and cold sharp changes is also very good. After 10 cycles of -40 ℃- 70 ℃ were tested by five Saibao laboratories in Guangzhou (designated testing centers of key research institutes), all of them passed.

The vacuum outgassing of Fluorophlogopite mica is low, and the trace gas released by the mass spectrometer is only O2, N2 and Ar. Since no H2O vapor is released, it is very valuable for electric vacuum insulation materials, which can greatly improve the service life of vacuum devices.

Natural mica decomposes H2O and other volatile components at high temperatures, so it is not suitable for electric vacuum insulation materials. The amount of vacuum outgassing of natural mica is high, which is 2000 times higher than that of Fluorophlogopite mica at about 900 ℃.
Fluorocrystalline mica is an ideal electrical insulation material in the field of high-end technology. It has been selected by the 13th Institute of Shijiazhuang of China Power Group as insulating sheets for space equipment such as the Shenzhou 8 spacecraft and environmental monitoring satellites.

vacuum insulation field Fluorophlogopite, a type of mica mineral, has shown promise in the field of vacuum insulation. Due to its excellent thermal and chemical stability, low thermal conductivity, and resistance to high temperatures, fluorophlogopite is being explored as a potential material for vacuum insulation applications. Its ability to maintain structural integrity in extreme conditions makes it an attractive candidate for use in vacuum insulation panels, which are utilized in various industries for efficient thermal insulation. The unique properties of fluorophlogopite offer the potential to enhance the performance and longevity of vacuum insulation systems, contributing to improved energy efficiency and thermal management in diverse applications ranging from refrigeration to aerospace technologies. Ongoing research and development efforts aim to further explore the suitability of fluorophlogopite for vacuum insulation and expand its impact in this critical field.
