Product Information

Alumina ceramic, also known as aluminum oxide or Al2O3, is an oxide ceramic widely used in industry. Alumina ceramic materials are known for their extremely high hardness and high thermal conductivity. The properties of alumina ceramics make it one of the most widely used ceramics in structural, wear and corrosive environments.

Aluminum oxide is characterized by high hardness, corrosion resistance, thermal stability, good dielectric properties (for conversion from DC to GHz frequencies), low loss tangent and stiffness.

Alumina ceramics are divided according to the Al2O3 content in the material. Common ones are: 75%, 95%, 99%, 99.5%, 99.7% alumina ceramics, etc. Usually, we choose the purity of alumina ceramics based on the performance requirements of the products we make.

Product Categories

1. Alumina Ball

Alumina balls are non-spherical aluminum oxide particles that are widely used in the petrochemical, agricultural and coatings industries.

Alumina balls can directly enter the reaction, greatly reducing the impact on the catalyst, thereby extending the service life of the catalyst. In addition, alumina balls can also be used to make surface protective coatings. After spraying on metal, plastic and other surfaces, it can improve surface hardness, corrosion resistance, wear resistance and flame retardancy.

In the electronics industry, spherical alumina balls are of great significance in the field of electronic packaging because of their excellent electrical, thermal and mechanical properties.

Particle size range: 0.3-0.4, 0.4-0.6, 0.6-0.8, 0.8-1.0, 1.0-1.2, 1.2-1.4, 1.4-1.6, 1.8-2.0, 2.0-2.2, 2.2-2.4, 2.8-3.0, 3.0-3.2, 3.2-3.5, 4.5-5.0, 5.0-5.5, 6.0-6.5, 6.5-7.0, 8, 10, 12, 15, 20.

4. Composite Ceramic Lining

Features: Ceramics have the characteristics of high strength, wear resistance, corrosion resistance, and smooth outer wall, but ceramics are relatively brittle. Rubber has good impact resistance and is combined with ceramic to form a strong wear-resistant layer, which can buffer the impact during the transportation of larger materials and better protect equipment. Used in anti-wear of troughs, hoppers and other equipment.
