Calcined Alumina Powder

This series of products are refined with advanced formula and strict process. Calcined alumina powder has reasonable particle size distribution, good particle fluidity, loose bonding between grains, good grindability and easy sintering. Its porcelain parts are dense, smooth surface, high mechanical strength, good electrical insulation, it is an ideal raw material for the manufacture of special ceramics.

Calcined alumina powder according to different use requirements, five series of products have been formed, including dry pressing, isostatic pressing process series, hot die casting, grouting molding series, refractory material series, pouring molding series, and alumina structural ceramic granulation powder.

Calcined alumina powder has a high melting point, excellent mechanical strength, hardness, high electrical resistivity and thermal conductivity. It can be widely used in industries such as electronic equipment, structural ceramics, refractory materials, wear-resistant materials, and polishing materials.

1. Dry pressing and isostatic pressing process series:

This series of products are refined with advanced formula and strict process. The product has reasonable particle size distribution, good particle fluidity, loose bonding between grains, good grindability and easy sintering. Its porcelain parts are dense, smooth surface, high mechanical strength, good electrical insulation, it is an ideal raw material for the manufacture of special ceramics.

2. Hot die casting and grouting molding series:

This series of products has large primary grain size, stable performance, good molding performance, small product shrinkage, and wide application range. It is especially suitable for hot die casting and grouting molding series, and can be used for various high temperature resistant Grinding ceramic parts (screw pump shaft plug pump lining, impeller, grinding media ball, etc.), electronic substrates, electronic vacuum tubes, etc.

3. Refractory material series:

The crystal form of this product is stable, which can improve the refractoriness and mechanical properties of the product. It is suitable for the production of unshaped refractory materials (various high-alumina castables), shaped refractory materials (corundum bricks, etc.), furnace materials, etc., to meet customers' requirements High temperature, excellent thermal shock stability and processing characteristics are required to extend the service life of refractory materials.

4. Pouring molding series:

The product has uniform grains, good filling performance and pouring activity, which can increase the sintering density, high temperature flexural and compressive strength of the castable, and enhance the wear resistance, corrosion resistance and erosion resistance of the castable. It can be used for low-cement, ultra-low-cement or cement-free castables, shaped refractory materials and precision polishing.

5. Alumina ceramic granulation powder:

It is made by scientific research and batching, automatic grinding, pulping and spray drying. The particle size distribution is uniform, the fluidity is good, and the strength is moderate; the green body produced has high strength, excellent mold release performance, and low firing temperature; the product has a smooth surface and a compact structure. It can meet the technical requirements of rapid dry pressing of precision ceramics, and is an ideal raw material for the production of electronic ceramics and structural ceramic components.
