High Insulation Glazed Aluminum Oxide Ceramic Smooth Surface Customized Size
High insulation and smooth surface glazed alumina ceramic
1. Description
Alumina or aluminum oxide (Al2O3) in its various levels of purity is used more often than any other advanced ceramic material. Tigar 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.
