Product Detail

Al2O3 Aluminum Oxide Alumina Ceramic Plate


Alumina Ceramic is the most widely used advanced ceramic. After high pressure pressed and high temperature sintered, Al2O3 is hard, chemical inert, electrical insulated, good thermal shock and high temperature resistant. People can find components made of Aluminum Oxide in various industries, like plungers and pistons in pumps, trays and setters in MIM sintering process, thick film ceramic substrates in electronic devices, high voltage insulators in electrical industry... UNIPRETEC offers Alumina Ceramic in high purity range from 90% to 99.7%, besides, we are good at manufacturing Aluminum Oxide Components by dry pressing, cold isostatic pressing, injection molding, tape casting, slip casting...
