Alundum

Alundum is a brand name for a type of alumina-based abrasive material. It is primarily composed of aluminum oxide (Al2O3) and is known for its hardness and durability. Alundum is widely used in various industrial applications, including grinding, cutting, and polishing.

Properties

Alundum is characterized by its high hardness, which makes it an effective abrasive material. It has a Mohs hardness of 9, making it one of the hardest materials available. Additionally, Alundum is chemically inert and can withstand high temperatures, which makes it suitable for use in harsh environments.

Applications

Alundum is used in a variety of industrial applications, including:

• Grinding: Alundum is used in grinding wheels and other grinding tools due to its hardness and durability.
• Cutting: It is used in cutting tools and saw blades for cutting hard materials.
• Polishing: Alundum is used in polishing compounds and pads to achieve a high-quality finish on various surfaces.
• Sandblasting: It is used as a blasting media for cleaning and surface preparation.
• Refractory materials: Alundum is used in the production of refractory materials that can withstand high temperatures.

Manufacturing Process

The production of Alundum involves the fusion of high-purity alumina in an electric arc furnace. The molten alumina is then cooled and solidified into a crystalline form. The resulting material is crushed and sized to produce the desired particle size for various applications.
