Introduction to Calcined Alumina
Calcined alumina is a high - purity form of aluminum oxide (Al₂O₃) obtained by heating aluminum hydroxide at high temperatures. This process, known as calcination, transforms the raw material into a stable and highly crystalline form. Calcined alumina has a wide range of applications due to its excellent properties such as high hardness, high melting point, good chemical stability, and high electrical insulation. It is commonly used in industries like ceramics, refractories, abrasives, and electronics.
