Product Description

Alumina Ceramic High Temperature Ceramic Lining Tile/Plate

Num Oxide, is a durable fine industrial ceramic that is commonly used in a variety of processing applications. Grind sintered alumina ceramics only using a diamond tool. Alumina ceramic exhibits exceptional hardness and wear resistance, as well as low corrosion, excellent electrical insulation and bio-inertness. Alumina (Al2O3) is a very heat-stable ceramic material of excellent temperature stability.

Al2O3 ceramics with a purity of 95% to 99% are the most commonly used kind of technical ceramics. We offers a variety of alumina ceramic shaping methods, including molded injection, die pressing, slip casting, extrusion, and cold isostatistically pressing. Alumina is used in a wide spectrum of purity concentrations, ranging from ultrapure to added-substance grades. Although the purity of Al2O3 in finished products usually ranges between 90 and 99.8%.
