Alumina is an excellent high temperature ceramic material due to its high temperature stability. It is the most commonly used type of advanced ceramic and is available in purities ranging from 95 – 99.5%. Great Ceramic has access to many different types of Alumina including: injection molded, die pressed, isosostatically pressed, slip cast, and extruded.
High Temperature Ability – Alumina can be used in both oxidizing and reducing atmospheres up to 1650°C (2900°F) and in vacuum environments up to
2000°C (3600°F). Abrasion Resistant – Alumina is a very hard ceramic and is excellent at resisting abrasion. It is ideal for wear-resistant inserts or products.
Electrical Insulator – Alumina is commonly used as a high temperature electrical insulator, particularly the higher purity grades which offer better resistivity.
Chemical Resistance – Alumina offers good resistance to strong acids and alkalis at elevated temperatures and is ideal for applications where resistance to corrosive substances is required.
Great Ceramic has rich experience in milling, grinding and polishing precision (Advanced) ceramics and firing ceramics, which enables us to achieve:
- We can provide customized service according to technical drawings or samples;
- The smallest aperture of laser processing is 0.03mm;
- When the product thickness is less than 1.5mm, the general dimensional accuracy is controlled within ± 0.02mm;
- When the product has high precision requirements, the precision can be controlled within 0.01mm according to the requirements;;
- Please contact us for other details of the structure.
All tolerances can be improved upon depending on the size, shape & geometry of the technical ceramic part. Great Ceramic is dedicated to ensuring we make only the highest quality parts that meet or exceed our customers specifications.
Great Ceramic has accumulated many years of experience in the pursuit of developing the best precision (Advanced) ceramic parts in the world, and is constantly applying this knowledge every day. In fact, we have been involved in the production of precision ceramics by many customers.
