Alumina is an inorganic substance with the chemical formula Al2O3. It has high hardness, high melting point and boiling point, and is an ionic crystal.
Alumina is an important industrial material with a variety of uses. It is chemically stable and insoluble in water, but soluble in strong alkalis and strong acids. Alumina has a variety of crystal forms, including α-Al2O3, β-Al2O3 and γ-Al2O3, of which α-Al2O3 is the most stable phase. Alumina is usually prepared by industrial methods such as the Bayer process and sintering process, extracted from raw materials such as bauxite.

Alumina has a wide range of applications, including but not limited to refractory materials, abrasives, polishing agents, catalysts, adsorbents, and raw materials for smelting aluminum. In addition, alumina has special uses, such as thermal barrier coating materials in spacecraft to protect spacecraft from extreme temperatures.
The chemical properties of alumina make it an important industrial raw material. Its high melting point and hardness make it suitable for high temperature environments, while its insoluble nature in water gives it unique advantages in many industrial applications.
