Industrial alumina ceramics are widely used in advanced ceramics, due to its light weight, abrasion resistance and other excellent properties. Now in run alumina zirconia ceramic factory tells you the performance of industrial alumina ceramics has what advantage.
Alumina ceramic is a kind of ceramic material with alumina as the main body, used in thick film integrated circuit.
Industrial alumina ceramics have good conductivity, mechanical strength and high temperature resistance. Need to pay attention to is to use ultrasonic washing.
Industrial alumina ceramics are divided into high purity type and common type.
The content of Al2O3 in high purity industrial alumina ceramics is 99. More than 9% of industrial ceramic materials, due to its sintering temperature as high as 1650-1990 ℃, transmission wavelength of 1 ~ 6 muon, generally made into molten glass to replace the platinum crucible; Use its transmittance and alkali - resistant metal corrosiveness as sodium lamp tube; It can be used as integrated circuit board and high frequency insulation material in electronics industry.
Ordinary industrial alumina ceramics are divided into 99 porcelain, 95 porcelain, 90 porcelain, 85 porcelain and other varieties according to the content of Al2O3. Sometimes, those with Al2O3 content of 80% or 75% are also classified as ordinary industrial alumina ceramics.
Performance advantages of industrial alumina ceramics:
1. The hardness
Measured by Shanghai institute of ceramics, Chinese Academy of Sciences, its rockwell hardness is hra80-90, the hardness is only second to diamond, far more than the wear resistance of wear resistant steel and stainless steel.
2. Good wear resistance
According to the measurement of powder metallurgy institute of central south university, its abrasion resistance is 266 times of manganese steel and 171.5 times of high chromium cast iron. According to our customer tracking survey for more than ten years, under the same working condition, the service life of the equipment can be extended at least ten times.
3. Light weight
Its density is 3.5g/cm3, only half of that of steel, which can greatly reduce the load of equipment.
