Abstract:
This application discloses methods and processes for preparation of high purity aluminum hydroxide and high purity aluminum oxide. The method of preparing high purity aluminum hydroxide involves reacting aluminum with water in the presence of one or more catalysts and one or more complexing agents that can react with non-aluminum metal impurities to form soluble complexes for effective removal through rinsing.
