The tabular alumina powder takes the imported industrial alumina powder as the main material. Through special processing, grain growth direction is controlled by high temperature, the particles appears the unique plate-like structure, mohs hardness is up to 9 degree, it has the strong grinding force, not easy to produce scratches.
