Alumina Powder application fields and characteristics:
Refractory materials field
-Application: Manufacturing of refractory bricks, crucibles, high temperature seals, heat insulation panels, etc.
- Features: It has high melting point and good chemical stability, can withstand high temperature environments, and maintains stable performance in high-temperature industrial furnaces such as steel smelting furnaces and glass melting furnaces.
Ceramic industry
- Application: As an important ceramic raw material, it is used to produce various ceramic products such as ceramic tiles, porcelain, and porcelain bottles. It can also be used to manufacture ceramic knives, molds, etc.
- Features: It can significantly improve the strength, hardness and wear resistance of ceramics, making ceramic products stronger and more durable. It can also improve the high temperature resistance and chemical stability of ceramics.
Electronic industry field
-Application: Used in the manufacture of insulating layers, substrates, vacuum capacitor ceramic shells and semiconductor integrated circuit ceramic packaging shells in electronic components, etc.
- Features: It has large insulation resistance and good insulation performance, which can ensure the normal operation of electronic components and prevent problems such as current leakage and short circuit. Some alumina ceramics also have certain thermal conductivity, which helps electronic components dissipate heat.
Abrasive field
- Application: Made into sandpaper, grinding wheels, abrasive paste and other abrasives, used for grinding, polishing and grinding of metal and non-metallic materials.
- Features: High hardness enables it to effectively remove impurities and defects on the material surface to achieve ideal processing results, and is not easy to wear during the grinding process and has a long service life.
Catalyst carrier field
- Application: As a catalyst carrier, it is widely used in catalytic reactions in petrochemical, environmental protection and other fields, such as catalysts for the production of sulfuric acid, nitric acid, ammonia, etc.
- Features: It has a large specific surface area and good adsorption performance, which can evenly disperse the catalyst on its surface, improve the activity and stability of the catalyst, thereby improving the efficiency of the catalytic reaction.
Biomaterials field
-Application: Used for making medical ceramics, dental filling materials, bone repair or replacement materials, etc.
- Features: It is biologically inert, non-toxic, insoluble and resistant to high temperatures, acids and alkalis. It will not chemically react with human tissue, has high strength and wear resistance, and can exist stably in the human body for a long time.
Optical field
- Application: Transparent alumina ceramics can be used to make high-pressure sodium lamps, metal halide lamps, transparent ceramic armor, etc. Ruby, sapphire, etc. can be used in fields such as optical components, sensors, fiber optic sensor materials, lasers and substrate materials.
- Features: In addition to the high temperature resistance, corrosion resistance, high strength, high hardness and other properties of ordinary alumina ceramics, it also has functional properties such as light transmission, wave transmission, and laser light, and can withstand extreme high temperatures, magnetic fields, radiation and other harsh conditions.
Building materials field
- Application: production of fireproof boards, fireproof glass, non-combustible insulation materials, etc.
- Features: As a non-combustible material, it has good fire resistance and heat resistance, which can effectively prevent the spread of fire and improve the fire safety of buildings.
