How To Produce High-quality High-purity Alumina Powder
Apr 26, 2022
The preparation method of high-purity alumina powder is to dissolve aluminum hydroxide in the sintering method to produce alumina technology into sodium aluminate solution, carry out impurity removal treatment, and then add crystal seeds for seeding to prepare high-purity aluminum hydroxide. A sodium removing agent is added to the alumina and then the hydrothermal composition is carried out to obtain high-purity boehmite, and the boehmite is washed and roasted to obtain high-purity alumina.
Products are widely used in rare earth phosphors, lithium battery separators, high pressure sodium lamps and related special alumina precision ceramics.
