Product Description:
Calcined alumina is produced through the calcination (“heating”) of alumina to various temperatures. By controlling the calcination temperatures and time, the properties of the alumina can be controlled. Calcined alumina, also known as aluminum oxide, is a high-purity, white crystalline substance that is produced by heating aluminum hydroxide to a high temperature.
Key Properties:
- High temperature stability: Calcined alumina has a high melting point and is able to withstand high temperatures
- High electrical insulation: It has excellent electrical insulation properties
- Abrasion resistance: It is a hard and abrasion-resistant material
- Chemical resistance: Calcined alumina is resistant to many chemicals, including acids, alkalis, and organic solvents
- extreme hardness (9 on the Mohs hardness scale)
Applications:
- Structural ceramics, Technical ceramics, Polishing compounds for plastic, metal, and glass, Fillers for Rubber and Plastics, Friction – anti slip, Refractories, Paint & Coatings and Thermal Spray Powders
- medical implants, dental materials, and other biomedical applications
- grinding, polishing, sandblasting, precision casting, etc., for refractory materials
