Introduction to Calcined Alumina
Calcined alumina is a high - purity form of aluminum oxide (Al₂O₃) that is produced by heating aluminum hydroxide at high temperatures. This process, known as calcination, results in a material with excellent physical and chemical properties. Calcined alumina has high hardness, good thermal stability, high electrical insulation, and chemical inertness. These properties make it widely used in various industries, such as ceramics, refractories, abrasives, electronics, and catalysts. In the ceramics industry, it is used to produce high - strength and high - quality ceramic products. In refractories, it can withstand extremely high temperatures, making it suitable for lining furnaces. In abrasives, its hardness allows for efficient grinding and polishing.
