Alumina microbeads refer to high-performance inorganic materials with a diameter of micrometers. The main raw material is high-temperature calcined high-quality alumina powder,which is mainly made through mixing, crushing, grinding, molding, drying, sintering and other processes. It is as hard as diamond, with a Mohs hardness is 9, dense structure, corrosion resistance, high temperature resistance, high wear resistance, high strength, high hardness, large specific gravity, small size and no pollution Alumina grinding balls produced by our company are widely used in various industries.

APPLICATION

 Due to its excellent properties such as high hardness, high strength, high wear resistance, high specific gravity, small size, high temperature resistance, chemical corrosion resistance, and no pollution, it is widely used in  1different industries:

1.Grinding and polishing field: It has high hardness and wear resistance can helps to improve the polishing efficiency and quality. It can be used for grinding and polishing of metals, glass, ceramics and other materials.

2.Electronic and optical fields: It has high insulation and good thermal p

  roperties, and can be used as insulating materials and heat dissipation materials.

3.High temperature and refractory materials field: It can be used as a heat insulation material to reduce the transfer of heat in high temperature environments.

4.Filler and reinforcement material field: By adding alumina microspheres, the strength, hardness and wear resistance of composite materials can be improved.

5.Pigment field: It is also widely used in the manufacture of pigments, such as porcelain, glazes, coatings, etc.

6. It can be used for complex surfaces such as pipelines, material loading buckets, material conveyors, etc., and can form wear-resistant and durable coatings. It has excellent potential in industries such as chemicals.

7. In oil and gas field exploitation, ceramic microspheres are used to improve the corrosion resistance of materials and reduce density, thereby enhancing the service life and working efficiency of oilfield equipment.
