Applications

Glass industry

Adding aluminium oxide white powder to glass can increase chemical stability, reduce the possibility of glass deterioration and ensure the whiteness of glass.

Ceramic industry

Abrasive aluminium oxide is the main component of ceramic clay. The higher the alumina content, the better the ceramic quality.

 

Electronic industry

Aluminium oxide al2o3 powder has excellent dielectric properties. It is used as a variety of circuit substrate, tube socket, shell, radome and so on in electronic industry.

High temperatyre insulation material

High temperature aluminium oxide single crystal can be used as laser components, instrument shaft bowls, bearings, decorations, etc. transparent products can be used as lamps, microwave fairing.

 

Abrasive tools

Aluminium oxide spherical has high hardness and high strength. It can be used as mechanical parts, various molds (wire drawing die, pencil lead extrusion die mouth, etc.), cutting tools, abrasives, armor protection materials, human joints, sand blasting, etc..

Refractories

Alumina plays an important role in the improvement of shaped and unshaped refractories. Filling it in the pores of refractories can improve the bulk density of the materials, greatly improve the heat resistance of the materials, achieve the ideal thermal performance and increase the strength of the materials.
