Customize High-pure 99% Alumina Ceramic Plates
Description:
Alumina or aluminum oxide (Al2O3) in its various levels of purity is used more often than any other advanced ceramic material. Alumina Ceramic offers a wide range of material types with different property profiles that can be adjusted via a targeted matrix design.
This material has very high hardness, very high stiffness, very good corrosion resistance to chemicals at high temperature, and very high refractoriness or use temperature.
