Introduction to Alumina
Alumina, also known as aluminum oxide (Al₂O₃), is a white, odorless, and crystalline powder. It is one of the most widely used ceramic materials due to its excellent properties. Alumina has high hardness, good wear - resistance, high melting point, and excellent electrical insulation. These properties make it suitable for a wide range of applications, including abrasives, refractories, electrical insulators, and as a raw material for the production of aluminum metal. In the metallurgical industry, alumina is the primary feedstock for the electrolytic production of aluminum. In the non - metallurgical sector, it is used in the manufacturing of advanced ceramics, such as cutting tools, dental implants, and electronic components.
