What is the Main Function of Alumina Powder?

Alumina powder is an integral component of many ceramic products. It’s used for making tiles and making wear resistance ceramic; additionally it serves as a catalyst carrier. Produced by mixing aluminum hydroxide with water and heating it at high temperatures, alumina is produced. Calcined alumina can be distinguished by their crystal size and sodium content. Materials with lower sodium contents are suitable for electronic applications or ceramic substrate.

It is a refractory material

Refractory ceramic are an inorganic non-metallic material with exceptional heat resistance that are ideal for industrial furnaces, boilers and kilns. Their heat capacity, thermal conductivity and erosion resistance properties can be customized precisely. They are utilized in furnaces, boilers and kilns among others applications; their capabilities make them versatile materials in numerous industrial settings including furnaces, boilers and kilns – often providing efficient heat resistant applications in demanding applications such as furnaces, boilers or kilns – while being fine tuned to meet specific characteristics like heat capacity, thermal conductivity or erosion resistance if required.

we provide a range of alumina powder testing capabilities, from feasibility to batch processing. Engineers can utilize these tests to fine-tune formulations for specific application needs and assess environmental impacts; additionally they may determine suitability of refractories for specific environments depending on factors like thermal shock resistance, chemical compatibility with molten metals/slags compatibility and dimensional stability.

It is a catalyst carrier

Alumina is an invaluable catalyst carrier, due to its chemical inertness and porous structure. This property allows it to assist chemical reactions within the petrochemical industry as well as providing environmental protection. Porous alumina can be manufactured through hydrothermal synthesis by reacting aluminum hydroxide with water in a closed vessel at high pressures and temperatures, producing ultrapure nanosized particles of specific shapes and sizes that adhere to certain standards. This reaction results in high purity alumina particles of specific shapes and sizes which meet exact specifications. Sintered Alumina particles can then be sintered together to form dense, strong ceramics with various industrial applications.

It is a heat dissipation material

Alumina is an outstanding heat dissipation material with low thermal expansion rates and an electrical insulator property, making it useful in electronics applications. alumina powder is an efficient heat dissipation material with high thermal conductivity (30-36 W/m · K), low thermal expansion coefficient, good chemical stability, and electrical insulation performance. It is widely used in electronic devices, new energy vehicles, 5G communication, and other fields.

Alumina powder is typically white or off-white in color and features a crystalline structure. It may also be dry pressed, isostatic pressed, hot pressed extruded, tape cast, injection molded and mixed with various organic or inorganic lubricants, plasticizers or electrolytes for use.
