Alumina Ceramic Plate

Properties of Alumina ceramic Plate:

The alumina ceramic plate 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.
