High purity alumina characterized with minimum concentration of 99.99% is high end form of aluminum oxide. Owing to its superior properties such as high purity, corrosion resistance and hardness, HCL leaching high purity alumina is extensively used as an essential material in LEDs and artificial sapphire glass. High purity alumina is produced by two methods namely hydrolysis and by leaching with hydrochloric acid. In hydrolysis method, aluminum oxide is produced from aluminum and alcohol. The aluminum oxide formed, further undergoes hydrolysis and calcination to obtain high purity alumina. The significance of this method is that the acid used in the process can be recovered and reused. Hydrochloric acid leaching method is on the verge of commercialization. With the success of HCL leaching method, the production cost of high purity alumina is expected to reduce significantly.
Demand for HCL leaching high purity alumina is expected to increase due to increasing adoption of LED products, smart watches, sapphire glass, and lithium-ion batteries. High purity alumina is also used in protective coatings for aircraft, aircraft engine, farm machinery, cars, and fuel cell. It is also used in production of scratch resistant semiconductor wafers, which are the basis of any electronic device. High purity alumina ceramic is also used in production of luminous tubes that are resistant to reaction with high temperature sodium vapor.
