Changchun Taiyuan Fluorogold Mica Co., Ltd. is the only domestic research and production unit for fluorophlogopite crystals.
The ideal electric vacuum device device - fluoride crystal Mica Sheet
The amount of evaporating gas from the fluorocrystalline mica is low, and the trace gases emitted by the fluorocrystal mica are only adsorbed gases such as O2, N2, and Ar. Since the H2O vapor is not released, this is extremely valuable for use as an electrical vacuum insulation material, and can greatly contribute to the service life of high vacuum devices.
Natural mica is required to decompose H2O and other volatile components at high temperatures and therefore is not suitable for use as an electrical vacuum insulation material. Natural mica has a high volume of air into the air, which is 2000 times higher than that of fluorite mica at about 900°C.
The ideal infrared Window Material - fluoride crystal mica sheet
The fluorite mica is parallel extinction, positive extension, interference color of the secondary gate, negative light of the secondary crystal, and the optical axis angle is about 10°. Since the fluorite mica contains less impurities, its light transmittance is relatively high from the ultraviolet to the infrared. For UV light, natural mica is basically impervious, and fluorocrystalline mica can penetrate nearly 0.2 υm. Natural mica has a distinct absorption peak at 2.75 μm, but no fluoride crystal mica, which is an important indicator that F ˉ replaces (OH) ˉ. From this, it can be seen that the fluorite mica is also a good light-transmitting material from ultraviolet (0.2υm) to infrared (5υm).
The fluorite mica is a book-like structure that can be stripped, completely cleaved, and can be stripped to the nearest 0.02 mm; flatness is very good,
It can reach atomic level; It is not easily deformed, can withstand greater pressure, and has high tensile strength and compressive strength; It is not aging, not easily broken, and it is not easy to adsorb impurities.
Due to its structural stability, fluoro-crystal mica is also a good light-transmitting material from ultraviolet (0.2 μm) to infrared (5 μm). It can work in the environment of 1100°C for a long time without affecting the material properties, and the infrared transmittance in the 2-5mm band can reach more than 90%. It is favored by kiln thermal imager system manufacturers (ie kiln body scanners). The infrared temperature measurement window used in the equipment replaces materials such as silicon, natural mica, and zinc selenide to ensure stable performance while greatly reducing costs. its
