Due to these outstanding properties, Ceramic Products are used in a wide range of industrial and advanced appications.

And a lot of practical applications prove that our ceramic products has reached a state of high standard and quality.

Properties of Alumina Ceramics
Alumina has a high melting point, high hardness and high mechanical strength, although mechanical strength is reduced at temperatures above 1000° C. Due to the relatively large coefficient of thermal expansion, thermal shock resistance is reduced. Alumina is an electrically insulating material, with a high electrical resistivity, increasing with purity. Good chemical stability of alumina, leads to a high corrosion resistance. It is insoluble in water and only slightly soluble in strong acid and alkaline solution.
Various Application of Alumina Ceramics
1. Seal rings
2. Medical prostheses
3. Laser tubes
4. Electronic substrates
5. Ballistic armour
6. Thermocouple tubes
7. Electrical insulators
8. Grinding media
9. Threadguides
10. Wear components
