High Dielectric Insulating Pink 96% Ceramic Al2O3 Plates

The prime features of ceramic al2o3 plate

1. High-Temperature Resistance, high Wear-resistance

2. Minimal warpage, bending, and undulation

3. Good smoothness/flatness with a full dense body

4. Physical and chemical properties are stable even in a harsh environment

5. Excellent thermal shock resistance. High thermal conductivity and coefficient of thermal expansion similar to that of silicon

6. Excellent electrical insulation properties, the high dielectric breakdown voltage

7. Excellent resistance against oil and chemical

8. Stable breaking strength, and less variance in shape or dimensions

Description of ceramic al2o3 plates

Al2O3, also known as alumina, is a hard-wearing technical ceramic material regularly used in a broad range of industrial applications. Al2O3 ceramic plates are frequently shaped by tape casting, dry pressed or Isostatic pressed and fully sintered under high temperature to be a strong and dense technical ceramic parts.
This kind of Industrial Ceramic Plate can be made of different purity alumina ranges from 95% to 99.8%, also we are able to cater to various custom specifications, such as different colors, different sizes, different designs, in addition to custom compositions for commercial and research applications and new proprietary technologies.
In order to reach some special application, like enhance 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-like polishing, glazed surface, high precision machining, and metalized.
We have the capability in producing small to large size ceramic al2o3 plates, whatever, it's a prototyping case or high volume project, we could provide you an ideal solution. Besides, we are dealing with a variety of ceramic sheets, Metallized Ceramic Substrate in different technical ceramic materials.

Application of ceramic al2o3 plate

Alumina Ceramic plates are mainly used in high-power equipment, IC MOS tubes, IGBT patch thermal insulation, high-frequency power supply, communication, mechanical equipment, high current, high voltage, high temperature and other product components that require thermal insulation and so on.
