Ceramic plates made of alumina ceramic (Al2O3 ceramic) have high thermal conductivity, compressive strength, and thermal shock resistance and can withstand high temperatures and maintain high strength and hardness. Alumina plates also have excellent electrical insulation and corrosion resistance. The excellent comprehensive properties creat a wide application fields for alumina plates, they are widely used in mechanical, electric & electronic, chemical, semiconductor etc.
Mascera offers tailor-made alumina plates in a wide range of purities, 95%, 96%, 99%, 99.5%, 99.8%. The higher purity has less impurities and is able to use for vacuum applications. The ceramic plates are produced through high tempeature sintering and are fully dense. The surface finish of alumina ceramic plates can be as fired, fine grinding or polishing, the geometry can be machined into tight tolerance to meet high fitting requirements. We work closely with our customers to understand what they need and produce the exact ceramic parts. No matter small quantity for prototype or big quantity for batch production, we are always ready to provide our service.
