Alumina Ceramic Plate Properties :
The alumina ceramic plate for industrial is made of Al2O3 as the main raw material and rare metal as the flux through 1700 ° high temperature sintering. Through mold making, aluminum oxide powder batching, grinding, milling, pressing, sintering, grinding, inspection and packaging, the molding process of different products is different, and the general molding includes dry pressing molding and isostatic pressing molding. The prices of the products produced will be different according to the different production technologies.
Because of its high temperature resistance, high strength, good wear resistance, good insulation, corrosion resistance, chemical stability and other characteristics, aluminum oxide plate is widely used in the environment with high temperature resistance, insulation, heat insulation and other requirements.

The description of industrial ceramic plates
Industrial 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 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 polishing, glazed surface, high precision dimensions, and super flat surface and metalized.
