Alumina balls, composed of greater than 99% sintered alpha-alumina with very low impurity levels, are essentially inert in most chemical environments.

The low silica content makes an excellent choice for high temperature applications in the presence of high water partial pressures, where silica leaching must be held minimal, such as in reformers for synthesis gas production.

The low level of other impurities makes an excellent recommendation for supporting adsorbents used to purify reactive monomers such as ethylene and propylene.
The ultra low porosity, very high density and outstanding thermal shock resistance of make them ideal for regenerative burner and filtering media for the metals industry.

Brasion-resistant Alumina Wear Linings
The microlite alumina abrasion-resistant linings is formed by dry pressing and fired at 1500°C in furnace. Alumina wear linings is one special ceramic material with a Rockwell hardness of HRA80-90, almost equal to diamond.
The alumina wear linings is abrasion resistant, impact resistant and easy for installation, the abrasion resistance is 260 times of manganese steel and 170 times of chrome steel in theory. In actual practice, the alumina wear linings can prolong the service life of the wear parts of the equipments.

Alumina wear linings is mainly used as protective linings for powder material transportation pipeline and powder concentrator equipment in the steel works, thermal power plant and cement industries
