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.
