Alumina ceramic parts Customer customization High temperature resistance
Product description
Alumina ceramic are usually prepared by sintering process. First, the original powder of alumina ceramic, usually alumina powder, is prepared by powder metallurgy. The original powder is then sintered at high temperature and pressure through process steps such as molding, pressing and sintering, so that the powder particles are combined into dense ceramic materials.
Alumina ceramic is a high performance material with excellent physical and chemical properties. It is composed of alumina (Al₂O₃), alumina ceramic combines the hardness of sapphire and the high temperature resistance of ceramic, becoming a multi-functional material.
It has a wide range of applications in various fields, including optical equipment, semiconductor manufacturing, electronic devices, high-temperature tools and equipment, chemical industry, etc. Its excellent properties make it the material of choice in many critical applications.
We offer customized alumina ceramic products, designed and manufactured according to our customers' needs. Whether high hardness, high temperature resistance, chemical stability or optical transparency are required, our sapphire ceramics meet a wide range of demanding applications.

Product characteristics
Temperature characteristics:
- Temperature range: Alumina ceramics usually operate at high temperatures and have good thermal stability. Common use temperatures range from 1000°C to 1800°C, depending on the composition and structure of the material.
- Coefficient of thermal expansion: The coefficient of thermal expansion of alumina ceramics is usually between 4 and 9 x 10^-6/°C, which indicates the linear expansion rate of the material as the temperature changes.
These are just some of the application areas and characteristics of alumina ceramics, and its wide application and versatility make it favored in various industries. Whether in industry, research or daily life, alumina ceramics play an important role and provide reliable solutions for many critical applications.
