Special Alumina
✹Product introuduction
Microstructure under scanning electron microscope
With quality raw material and advanced process, special alumina features wide application scope, high purity, centralized particle size distribution, good dispersity, uniform original crystal of powder and high crystallinity. It is mainly applied to coating of new energy battery diaphragm, precise polishing of electronic product and high property ceramics.
✹Product features
Diaphragm ceramics coating
Relatively low moisture content of coating diaphragm
Powder is easy to disperse and ceramics slurry has good placing stability
Small air permeability increasing and low heat shrinkable property after coating
Centralized particle size distribution and moderate hardness
Good product batch stability
Fine polishing
Good slurry placing stability and hard to deposit
No abnormally big particle
Low viscosity and good mobility of slurry
Near spherical structure and no edge
Special ceramics
01 Centralized particle size distribution
02 Moderate particle activity, good sintering property and sinter to ceramics under extremely low temperature
