Specifications:
Alumina ceramic is a kind of structural ceramics which widely used in electronic ceramic substrates, ceramic electrical insulation, vacuum devices, devices porcelain, spark plugs and other products.
The alumina ceramic have many advantages as follows.
1.High mechanical strength
2.Low loss in high frequency
3.High dielectric strength
4.Low gas leakage coefficient
5.High voltage resistance
6.High dimensions precision
We can make the part by hot injection pressing, dry pressing, isostatic pressing and extrusion productive technology, etc.
