Fluorocrystalline mica, also known as Fluorphlogopite Mica, synthetic mica, artificial mica, synthetic mica crystal, belongs to the silicate type artificial mica crystal, is under the high temperature condition of 1500°C, through strict process conditions and material ratio, in platinum The mica crystals smelted in the yttrium have a chemical formula of KMg3(AISi3O10)F2(OH)-, and do not contain (OH)-. The (OH)-hydroxyl group is replaced by F-(fluoro), which is similar to the fluorite mica. Materials commonly used in the general industry are natural mica. Natural mica is an underground ore naturally formed and belongs to the class of silicates. Most of the industrial mica used is phlogopite (brown) and muscovite. Its ideal chemical formula is KAI2(AISi3O10)(OH)2. OH)-(Hydroxy), due to the presence of hydroxyl (water molecules), its performance in all aspects is far lower than that of fluorocrystalline mica.
The main characteristics of fluoride crystal mica:
1, high temperature: can work long-term in the 1100 °C environment.
The testing department of the Changchun Institute of Applied Chemistry, Chinese Academy of Sciences (nationally recognized testing institute) tested the thermal weight loss of 8% at 1100°C for 48 hours, and the melting and devitrification temperature was 1375°C.
2. Electrical insulation: The volume resistivity is 10 times higher than natural mica. Electrical breakdown strength is PTFE
Lean 10 times.
3, hot and cold blasting stability is very good

Inspection, all qualified.
4, anti-corrosion:
Fluorophlogopite does not react with acid and alkali solutions, and does not react with water. Under the long-term (2 to 3 years) scouring of high-temperature and high-pressure water (including acid and alkali), the original clarity and transparency can still be maintained.
5, high frequency performance:
The dielectric constant of fluorite mica is 4.6 ε, and the dielectric loss is (1~4)×10 −4 tg δ, and the dielectric loss is very low. And because of the pure texture, all parameters are extremely stable.
6, optical properties
Since the fluorite mica contains less impurities, its light transmittance is compared from infrared to ultraviolet.
High, the transmittance is close to 100%.
7, Mosaic (Mosaicity):
The Mosaicite of fluorocrystalline mica is less than 0.25 degrees, which was produced in the experiment.
The neutron flame is not high enough to absorb multi-band light beams and is an ideal neutron monochromator test material.
8, vacuum deflation performance:
The evaporative volume of fluorite mica is low, and it is measured with a mass spectrometer and the trace gas released is only
O2, N2, Ar and other adsorbed gases. Since the H2O vapor is not released, this is extremely valuable for use as an electrical vacuum insulation material, which can greatly increase the service life of the vacuum device.
9, excellent physical properties:
Fluorocrystalline mica has atomicity flatness, transparency, separability and elasticity, not aging
It is not brittle and so on.
Due to the high temperature resistance, corrosion resistance, low frequency loss, and high bulk resistivity
Absorb multi-band light beam, excellent light transmittance and other advantages. Therefore it has become an ideal new material in the high-end area.
Fluorocrystalline mica Available in:
In the range of 180mm×53mm or ∮76mm, it can be processed into various shapes according to user requirements. Thickness within the range of 0.02mm~1.0mm can be allocated according to user requirements. The conventional thickness is 0.04~0.2mm.

Today, driving safety becomes the first choice for consumers. The technological revolution of the global automotive brake system is changing with each passing day. However, the issue of “stopping†has become the most tangled issue for Chinese auto parts companies. According to a survey report from the AQSIQ defective product management center, from June 18, 2004 to December 28, 2009, there were 214 car recalls in China. Of these recalls, about 30% are related to defects in auto parts, among which key issues such as car braking are top of the list.
On the eve of the “2011 China Automotive Braking System Industry Development Strategy Summit Forumâ€, Mr. Xu Jinquan, CEO of China4Auto.com pointed out that the industrial upgrading of China's automobile brake system has reached a moment of urgency. At present, various countries have imposed increasingly stringent requirements on the braking performance of automobiles and developed detailed standards. At the same time, consumers are increasingly concerned about the braking performance of automobiles. For Chinese parts and components companies, it is time for technological innovation and product upgrading.
With the rapid development of China's automobile industry, the market for China's automobile brake system industry has also rapidly expanded. According to data detected by the China Association of Automobile Manufacturers, from January to October 2010, the export value of brake system component products was US$2.426 billion, an increase of 39.28% over the same period of last year. The major destinations for product exports are the United States, Japan, Canada, Germany, and the United Kingdom.
As the largest industry research team in the automotive industry, Jiazhidao Automotive Consulting Researchers analyzed that the expansion of the market cannot hide the hidden concerns behind related industries. Like the problems existing in China’s auto parts and components, the Chinese brake system industry, which relies on low-price competition, has not gone out of its predicament. On the one hand, high-end product development has been subjected to technical pressure from developed countries; on the other hand, the cost advantage of products has been affected. Low prices from emerging countries.
How does the Chinese automobile brake system industry seek to break through? From February 22 to 23, at the “2011 China Automotive Braking System Industry Development Strategy Summit Forum†to be held in Shanghai, the China Automobile Industry Association Brake Committee, the National Motor Vehicle Product Quality Monitoring Center (Shanghai), and the German motor vehicle Related personnel such as DEKRA and executives of Chinese auto parts companies will discuss this in depth.
More and more new technologies are being applied to the brake system. Electronic technology has become a trend of development. New technologies and new functions have brought new markets. For the related enterprises of the automobile brake system, What should be the direction of development during the period? What are the technical routes? How should the opportunities for development be grasped? At the same time, as the domestic after-sales market is becoming more and more substantial, the automotive aftermarket is also experiencing fierce competition and gradual standardization. In overseas export markets, enterprises must also face more and more stringent barriers to standardization of braking performance. What strategies should companies adopt in the process of opening up the market? The Summit, which is sponsored by the China Automotive Industry Association's Brake Committee, organized by China4Auto.com and co-organized by the China Europe International Business School Alumni Automobile Industry Club, will address these most pressing issues.
The China Automotive Consultation Center (china4auto.com) is a leading comprehensive market service provider for the Chinese automotive industry and related industry chains and is becoming the industry's most influential industry information publishing platform. Jiazhidao Automotive Consulting has also become the largest industrial research team in the automotive industry, providing industry customers with standardized data products and market consulting services.
The road to industrial upgrading of the automobile brake system is an urgent task
A new technology called predictive emergency braking (PEB) will be recently installed in the new Audi A8 model. When a vehicle encounters an emergency, this new braking system can automatically generate the maximum deceleration to avoid collisions, and the risk of injury can be minimized even if the collision is unavoidable. The use of PEB technology will greatly reduce the frequent rear-end collisions.
