| 外观 / 形态 : | Aluminum oxide is a white odorless crystalline powder. Water insoluble. Properties (both physical and chemical) vary according to the method of preparation; different methods give different crystalline modifications. The variety formed at very high temperature is quite inert chemically. alpha-Alumina is the main component of technical grade alumina. Corundum is natural aluminum oxide. Emery is an impure crystalline variety of aluminum oxide.
