Product Desciption

99.3% aluminum oxide corundum alumina ceramic material

1. Ceramic materials with Al2O3 content above 99.9% in high purity alumina ceramic series are generally made into molten glass instead of platinum crucible because of their sintering temperature as high as 1~6μm-1990ºC and transmission wavelength of 1-6 μ m: they are used as sodium lamp tubes by their light transmittance and alkali metal corrosion resistance; It can be used as integrated circuit substrate and high frequency insulating material in electronic industry.

2. Ordinary alumina ceramics are divided into 99 alumina, 95 alumina, 90 alumina, 85 alumina and other varieties according to the different Al2O3 content, and sometimes those with Al2O3 content of 80% or 75% are also classified as ordinary alumina ceramics. Among them, 99 alumina ceramic material is used to make high temperature crucible, refractory furnace tube and special wear-resistant materials, such as ceramic bearings, ceramic seals and water valve plates; 95 alumina porcelain is mainly used as corrosion-resistant and wear-resistant parts; 85 porcelain is often doped with talc, which improves its electrical properties and mechanical strength. It can be sealed with molybdenum, niobium, tantalum and other metals, and some of them are used as electric vacuum devices.
