Alumina
Aluminium oxide calcined
Aluminium oxide produced commercially is obtained by the calcination of aluminium hydroxide. Calcined alumina products are used in a wide range of ceramic and refractory applications. Alumina offers many specific properties - High compression strength, resistant to abrasion, chemically resistant, high hardness, high thermal conductivity, high dielectrical strength and resistant to thermal shock.
Uses for Calcined Aluminium Oxide:
- Ceramic materials such as Electronic devices
- Mechanical parts
- Whiteware
- Fillers for resin
- A key raw material for refractories and abrasives
- In pottery it is used to increase glaze viscosity, firing range and resistance to crystallization.
