High purity alumina was prepared by hydrolysis method

Hydrolyzed aluminium isopropanol

The method of alcohol-aluminum hydrolysis is often used in China, that is, in the presence of catalyst, the aluminum solution is obtained by mixing metal aluminum and organic alcohol, and then the high purity alumina product is obtained by hydrolysis and high-temperature calcination of the intermediate. The advantages of this method are high purity and small particle size of the prepared alumina products, while the disadvantages are high production cost, complex process and difficult process control.

Hydrolyzed high purity aluminum process

Firstly, the active powder metal aluminum was quenched, atomized, hydrolyzed and sprayed, and water resistivity & GT was separated by four-stage reverse osmosis and resin exchange process.12 meters Ω deionized water, using self-designed atomization device preparation of active aluminum powder atomization method, it combines supersonic atomization and centrifugal two methods;99.999% alumina products can be obtained after high purity aluminum is hydrolyzed in deionized water for some time.
