Application of α Alumina and γ Alumina in the Catalysis of Petroleum Refining |
What does alumina mean? Alumina Al2O3 is an organic compound with the chemical composition Al2O3. It has a high hardness and melting point of 2054degC. The boiling point is 2980degC. It's an ionic crystal which can be ionized at elevated temperatures. This is why it is frequently used for the production of refractory material. Alumina for industrial use is made from bauxite (3H2O*3O3) and diaspore. Chemical methods are used to prepare Al2O3 for high purity. Al2O3 is available in many crys
