99.7% Polished Alumina Al2O3 Ceramic Sheet
The prime characteristics of the alumina ceramic plates
1. Good smoothness/flatness to be 0.01mm and with min. warpage, bending, and undulation
2. Heat resistance and high-temperature resistance up to be 2000ºC under the vacuum atmosphere
3. Alumina offers diamond-like hardness, so it results in super wear-resistance than all metals
4. Physical and chemical properties are stable even in almost all strong acid and alkali conditions
5. Both high thermal conductivity and coefficient of thermal expansion are similar to that of silicon.
6. Excellent electrical insulation properties, high dielectric breakdown voltage, it's fit for electrical insulators
7. It's anti-aging and resistant against oil in various environments which is not rusted forever.
8. Stable breaking strength, and less variance in good shape or consistent dimensions each batch.
The specification of the alumina ceramic plates
1. Material : 96% alumina, 99% alumina, 99.5% alumina, zirconia, silicon nitride, silicon carbide optional
2. Dimensional capability Side length max. 500mm x 600mm, Thickness can be range from 0.15mm to 30mm
3. Surface treatment: natural surface, lapping, diamond-like polishing, metallization, glazed
4. We have many selections of al2o3 ceramic plates, refer to the checklist of standard sizes in different purity.

The description of alumina ceramic plates
Alumina ceramic plates are formed by tape casting, dry pressed or Isostatic pressed and sintered under high temperature to be a strong and dense ceramic part. We can produce different grades of materials to custom specifications by request, in addition to custom compositions for commercial and research applications and new proprietary technologies.
In order to reach some special application, like enhancing the insulation strength, dielectric, precision assembly, we always proceed with these ceramic alumina plates with the secondary process with our in-housing manufacturing types of equipment, including diamond polishing, glazed surface, high precision dimensions, and super flat surface and metalized.
