Alumina ball is a porous spherical material made from bauxite and fired at high temperatures. It is widely used in industrial scenarios such as drying and adsorption, catalyst carrier, grinding medium, and thermal insulation filler.

Where can alumina balls be used

Drying and adsorption: used for dehydration of compressed air and natural gas, as well as defluoridation and removal of heavy metals from drinking water.

Catalyst carrier: It is used to carry catalysts in petrochemical and fertilizer production to enhance reaction efficiency.

Grinding medium: High-alumina balls are used for fine grinding of ceramic glazes and chemical raw materials, featuring wear resistance and corrosion resistance.

Thermal insulation filler: The hollow spherical structure has low thermal conductivity, making it suitable for use as a thermal insulator in high-temperature furnace linings and refractory castables.

Thermal conductive filler: Spherical alumina is used in thermal interface materials and engineering plastics, exhibiting excellent thermal conductivity.
