Product Description

 

Alumina ceramics are one of the strongest ceramics available. Alumina ceramics have excellent properties, making them

one of the most widely used ceramics in structural, abrasive, and corrosive environments. In addition, high-purity alumina

ceramics have excellent electrical properties and are one of the materials of choice for semiconductor chamber

applications.

 

INNOVACERA Alumina includes many grades: 95% Alumina, 99% Alumina, 99.5% Alumina and 99.9% Alumina.
They can fulfill customers' different demands. The dimension ranges from 1mm to 500mm.

 

.Purity:92%,96% and 99.7% .Good mechanical strength
