CAS No.:11092-32-3
Aluminum Media Balls
Synonyms: Aluminum Balls, Alumina Balls
Molecular formula: Al2O3
Properties: Alumina balls generally refer to high alumina balls, which are a category of alumina balls and are referred to as high alumina balls due to their high alumina content. High alumina balls can be subdivided into 90, 92, 95, 99 and other series according to their alumina content.
Application
In the ceramics industry, there are data showing that using pebbles (natural ball stones) + 10% high alumina balls (φ35MM) for grinding diluted clay can reduce the grinding time by 15% compared to using only pebbles;.
In the quartz industry, alumina balls are mainly used to produce silica micronized powder.
In the drinking water industry, activated alumina is mainly used for the defluoridation of drinking water in high fluoride areas.
