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.

In the past year of 2006, the Chinese auto industry showed a strong side of its pillar industries: Domestic sales exceeded 7 million, and exports were expected to exceed 340,000, both of which were the highest ever. However, in the industry and outside of a carol, the inharmonic sounds of product quality have occurred from time to time, and even began to interfere with consumers' choice of brands. After achieving the breakthrough of “quantityâ€, the improvement and leap of “quality†will be the most important thing that China’s auto industry should do during 2007 and even the 11th five-year plan period.
As early as a dozen years ago, China was recognized as the world's last undeveloped automobile market: In the 40 years of development, the annual sales volume has reached only one million units. The car industry is basically blank, and the auto industry is in the seller's market as a whole. This supply and demand situation has continued into China's post-WTO period. As the production of vehicles under the planned economic system changed to private consumer goods under the market economy system, the demand for automotive products in the market was promoted, and in 2002 and 2003 there was an “explosive†increase. By 2006, the Chinese auto industry had finally landed on 7 million vehicles after it had stridden across several million steps. In order to solve the contradiction between long-term accumulation of consumer demand and short-term supply shortages, the Chinese auto industry has started to expand its production capacity projects since 2003. At the same time, strengthening marketing and construction has become a top priority for companies seeking to quickly occupy market share. Of course, both joint ventures and independent brands have introduced quality assurance systems that meet national standards when introducing advanced technologies and products. However, for most companies, the Chinese auto market is still in the “Warring States eraâ€, and it is the first time for the market to supply capacity and effective marketing methods. After the quality problem arises, the company’s after-sales service department will solve it. This "rapty radish is not washing mud" approach has indeed produced serious consequences, only from a Xinhua News Agency reporters can see with their own eyes: the new car replaced nine times a year exhaust pipe can not be used; Some new cars are used for tour, halfway down, air conditioning at 30°C does not work, and some foreign countries have exported 300 buses of a domestic brand to an African country. Most vehicles can't be driven in time.
The quality of the car not only appeared on the self-owned branded products, but also the joint venture brand car was also recovered by consumers. At present, cars used in China, especially vehicles sold in the past five years, will be at the peak of quality problems in the next year or two. If the company does not put the quality problem at the front end of the manufacturing process, and simply relies on the after-sales service department, then the product brand cannot be established, which will affect the survival of the company. The National Quality Inspection Bureau has issued regulations on the recall of defective automotive products. Once recalled, companies will bear huge losses.
The Central Economic Work Conference held at the end of last year proposed that the development of the national economy in 2007 should be changed from "fast and good" to "good and fast." For the Chinese auto industry, after reaching a certain number of platforms, 2007 will be the first year of quality. In the future, the growth rate of the auto industry will enter a stable period, and quality will be the most important factor in the business operations.
