Aluminum oxide ceramics are high-purity aluminum oxide products with excellent physical properties and chemical stability. The following are the performance characteristics and applications of alumina ceramics:
1. High hardness: Aluminum oxide ceramics have a very high hardness, up to level 9, which is more than 8 times that of steel. Therefore, they can be used to manufacture wear-resistant and high-temperature resistant components.
2. High melting point: Aluminum oxide ceramics have a high melting point of about 2050 ℃, making them suitable for use in high-temperature environments. For example, they can be used to manufacture high-temperature furnaces, heat exchangers, etc.
Aluminum oxide ceramics have a wide range of applications in industries, scientific research, military and other fields. For example, in automobile manufacturing, alumina ceramics can be used to manufacture wear-resistant components such as brake pads and clutch plates; In the aerospace field, alumina ceramics can be used to manufacture high-temperature engine nozzles, turbine blades, etc; In the medical field, alumina ceramics can be used to manufacture dentures, bone implants, etc; In the chemical industry, alumina ceramics can be used to manufacture reaction vessels, mass transfer equipment, and so on.
