Alumina 96%

Alumina 96% is a ceramic material with Al2O3 as the main crystal phase. SENCER PRECISION CERAMICS can produce ceramic products with an alumina content of 96% to 99.8%. Alumina is also called Al2O3 in the industry, with a density of 3.9~4.0 g/cm3, a melting point of 2050°C, and a boiling point of 2980°C. Alumina 96% ceramics have good dielectric properties, mechanical and heat resistance properties. In the production of functional ceramics, it is used to make UHF Insulation, modern large-scale integrated circuit housing, and substrate materials. The advanced ceramics made by alumina 96% are usually white, and different molding and sintering methods can be selected according to different uses of customers. The main pressing is usually Dry pressing, hot pressing, and injection molding depends on the structure of the ceramic parts.
