Square alumina ceramic plate

Alumina Ceramic Plate Advantage
1. High temperature and corrosion resistance: Made of 99.3% high-purity alumina material, it can withstand temperatures up to 1800℃. It is acid and alkali resistant, anti-oxidation, and not prone to aging or deformation under harsh working conditions.
2. High hardness and wear resistance: It ranks 8.5-9 on the Mohs hardness scale, with high flexural strength. It features excellent impact and collision resistance, and its service life is far longer than ordinary plates.
3. Excellent insulation and heat insulation performance: It has superior electrical insulation and low dielectric loss, as well as outstanding thermal insulation and heat preservation effect, suitable for electrical equipment and high-temperature kiln applications.
4. Standard size and easy installation: Standard square shape with high flatness. It is applicable for various installation scenarios such as equipment lining plates, heat insulation base plates and insulating substrate plates.
Alumina Ceramic Plate Application
1. Industrial high-temperature furnace heat insulation lining plate.
2. Electronic circuit insulating and heat-dissipating substrate.
3. Precision equipment wear-resistant protection base plate.
4. Laboratory high-temperature resistant bearing flat plate.
