Fiber optic connectors and optical fiber jumpers:
Ceramic fiber connectors and fiber skip connections are the most widely used and demanded optical passive devices in fiber optic networks. The core part of the single-mode multi-mode active fiber connector, the main component of which is zirconia ceramic sleeve (connector precision needle), the material used is yttrium oxide Y2O3 stabilized tetragonal zirconia powder. Its main uses are:
Zirconia ceramic bearing
Zirconia ceramic bearings have the characteristics of anti-magnetoelectric insulation, wear resistance, corrosion resistance, oil-free self-lubrication, high-temperature resistance, cold resistance and so on. They can be used in the extremely harsh environment and special working conditions.
At present, zirconia ceramic bearings have been used in miniature cooling fans. Their product life and noise stability are better than the traditional ball and sliding bearing systems. Foxconn took the lead in using zirconia ceramic bearings in computer cooling fans.
Zirconia ceramic valves
At present, metal valves are widely used in various industries in China. The use of metal valves has a history of more than 100 years. During this period, although the material and structure have also undergone changes, due to the limitations of metal materials themselves, the corrosion damage of metal on the wear resistance of valves has a period of time, reliability and service life. The effect of mechanical and corrosion factors on the metal greatly increases the total wear of the contact surface. During valve operation, the friction surface is worn and destroyed by the simultaneous mechanical action and the chemical or electrochemical interaction between the metal and the environment. The working climate of the pipeline is complex, and the presence of hydrogen sulfide, carbon dioxide and some organic acids in the medium of oil, natural gas and reservoir water increases the destructive power of the pipeline surface, thus rapidly losing its working ability.
Zirconia ceramics valve excellent wear resistance, corrosion resistance, high-temperature thermal shock resistance, can be competent in this field.
Zirconia abrasives
Zirconia grinding balls have high hardness, low wear rate, long service life, can greatly reduce the pollution of grinding raw materials, can well ensure product quality, at the same time, the density of zirconia materials, when used as grinding media, impact energy is strong, can greatly improve the grinding dispersion efficiency, can effectively shorten the grinding time.
Good chemical stability determines its corrosion resistance and can be used in acidic and alkaline media.
The wear rate of zirconia ceramic grinding balls is only 0.04/24h. It is widely used as grinding media in ball mills, vibrating mills, planetary mills, and agitating mills.
Zirconia functional ceramics
Generally speaking, zirconia ceramic balls for ballpoint pens are mainly made of stainless steel and tungsten carbide. However, such balls often break lines, drop beads, dead beads and dip in the first place.
Zirconia ceramic tool
Zirconia ceramic knives have the characteristics of high strength, wear resistance, no oxidation, no rust, acid and alkali resistance, anti-static, and no reaction with food. At the same time, the body of the knife is as bright as jade. It is an ideal high-tech green knife in the world. At present, the main products on the market are zirconia ceramic knives, scissors, razors, scalpels. In recent years, it has become popular in Europe, America, Japan, and Korea.
Zirconia high-temperature heating material
Zirconia is an insulating material at room temperature. Its specific resistance is as high as 1015_ cm. It can conduct electricity when the temperature is raised to 600 C. It is a good conductor when the temperature is above 1000 C. It can be used as a high-temperature heating element at 1800 C. The highest working temperature can reach 2400 C. It has been successfully used in heating element and its equipment under oxidation atmosphere above 2000 C. The electrode materials of MHD power generation are also actively studied.
Zirconia bioceramic materials
In the family of porcelain-fused-to-metal teeth, the quality of porcelain-fused-to-metal (ZrO_2) dental materials has a direct impact on its quality and health of patients. Because the internal crowns of porcelain-fused-to-metal (PFM) teeth are made of different metal materials, the internal metal crowns are prone to oxidative reactions with saliva in the mouth. Good transparency, excellent gloss, more effective to avoid teeth allergy and gingival black line and other issues, with enough good shading ability, can solve the teeth of patients with severe tetracycline teeth cosmetic needs, and zirconia material toughness to make up for the common porcelain teeth easily missing, good biocompatibility, no stimulation Oral mucosa is easy to clean. It is the best quality porcelain tooth at home and abroad.
Zirconia coating material
Zirconia thermal barrier ceramic coatings stabilized by high-performance stabilizers such as Y2O3 are mainly used in high-performance turbine aero-engines.
Zirconia communication materials
In recent years, with the development of new industries such as information and communication, the products of zirconia ceramics are becoming more and more precise and miniaturized. Toughened zirconia ceramics have excellent mechanical properties, corrosion resistance and high insulation performance, which can be competent for this field. In the ceramic PC type optical fiber active connector, the two zirconia pin body is the key component.
Zirconia oxygen sensor
Oxygen sensors are indispensable in the automotive industry when using a three-way catalytic converter to reduce emissions. There are two kinds of oxygen sensors, titanium oxide, and zirconia, among which zirconia oxygen sensors are the most widely used.
As early as the mid-1970s, Japanese automobile production technology is complete but difficult to enter the U.S. market, but the U.S. formulation of new policies to limit automobile exhaust pollution to Japan has brought opportunities, Japanese scientists made zirconia porous oxygen sensor, installed in the engine automatic detection.
