Calcined alumina powder can be applied in the following industries:
Abrasive and grinding tool field
It can be used to manufacture grinding tools such as grinding wheels, sandpapers, grinding heads, and grinding discs, and to use its high hardness characteristics for grinding materials such as metals and ceramics.
In precision casting, calcined alumina powder can be used as a refractory material for the shell, improving the strength and high temperature resistance of the shell.
Ceramic materials field
Calcined alumina powder is an important raw material for the production of structural ceramics, such as alumina ceramic bearings, ceramic cutting tools, ceramic seals, etc. It has advantages such as wear resistance, high temperature resistance, and corrosion resistance.
Can be used to manufacture electronic ceramics, such as integrated circuit substrates, capacitor ceramics, etc., with good insulation performance and thermal stability.
Refractory materials field
Calcined alumina powder is used to produce refractory bricks such as high alumina bricks and corundum bricks, and is widely used as the lining of high-temperature industrial kilns in metallurgy, chemical industry, building materials, and other fields.
Calcined alumina powder can be used as aggregate and powder for amorphous refractory materials, such as refractory castables, plastics, etc., for repairing kilns and overall pouring.
Electronic and electrical field
Calcined alumina powder can improve the thermal conductivity and insulation properties of electronic packaging materials, and is used for heat dissipation packaging of high-power devices.
Can be used to manufacture spark plug insulators, utilizing their high temperature resistance and insulation properties to ensure the normal operation of the engine.
Automotive industry field
Calcined alumina powder is used for coating automotive engine components such as pistons and cylinder walls, which can improve the wear resistance and high temperature resistance of the components and extend their service life.
In the carrier of automobile exhaust purification catalysts, aluminum oxide powder has a large specific surface area, which can improve the activity and stability of the catalyst.
