Product Description
| 99% Alumina ceramic plate with holes Alumina ceramics are ceramic materials based on alumina (Al2O3). Alumina ceramics is a versatile ceramic. Because of its superior performance, it has been widely used in modern society, satisfying the needs of daily use and special performance. |
Advantages of Al2O3 Ceramic1.High temperature resistance: 1600℃.2. Have good heat radiation and anti-corrosion.3. Good thermal conductivity .4. High strength and high density.5. Excellent heat-shock resisting ability. | |
| Alumina ceramic application: Alumina ceramics are classified into high-purity type and ordinary type. The high-purity alumina ceramics have a Al2O3 content of 99.9% or more. It can be used as an integrated circuit substrate and high-frequency insulation material in the electronics industry. |
Alumina ceramic classification: Ordinary alumina ceramics are classified into 99 porcelain, 95 porcelain, 90 porcelain, 85 porcelain, etc. according to the content of Al2O3. Sometimes the content of Al2O3 is 80% or 75%, which is also classified into ordinary alumina ceramic series. | |
