Description
Alumina packing ball Aluminum oxide powder is calcined into industrial powder, and then calcined into dense structure in rotary kiln and tunnel kiln at high temperature. This dense structure with stable chemical properties looks like ceramics, so it is called alumina ceramic ball. Different from general ceramics, alumina ceramic has a Mohs hardness of 9, second only to diamond, and its compressive strength and impact resistance are far from that of ceramics. At the same time, it has the same advantages as ceramics: acid and alkali resistance and corrosion resistance. These good properties make inert alumina packing balls more and more widely used in industry.
