Review of Impurity Removal Methods in the Preparation of High Purity Alumina With Aluminum Alkoxide Hydrolysis of Aluminum Alkoxide Hydrolysis Technology

Several processes/methods of impurities removal during high purity alumina preparation with aluminum alkoxide hydrolysis method were reviewed. These processes can be classified into three categories, i.e., aluminum alkoxide, aluminum hydroxide and alumina. After analysis of their fundamental principles of each process, advantages and disadvantages of every process, including operating parameters, performance characteristics and removal effect, were compared and summarized. Future development of the impurity removal technology was also prospected.
