Alumina Ceramic Plates Multi-Functional and Multi-Size Ceramic Plates

As a manufacturer of alumina ceramic plates, we manufacture and sell multi-size alumina ceramic plate like: alumina panels, alumina disc, alumina board, etc.and also offer custom or machining alumina plate for our customer.

Our alumina plate made by Al2O3 alumina ceramics which alumina purity can be option from 95% to 99.99% Al2O3.Alumina plates with different alumina Al2O3 content have different performance characteristics, so different types of alumina plates are used in different industries.

Alumina ceramic is a kind of alumina (Al2O3) as the main ceramic material.Alumina ceramics have good conductivity, mechanical strength and high temperature resistance.

For the alumina plate sizes we produce them according to customer requirements.high al2o3 purity, high precision,factory price.

Alumina plate Applications

Al2O3 Alumina ceramic plates are used in the following applications:

• Alumina plates are hard enough to become armor for personnel or vehicles.

• The corrosion resistivity of alumina plates makes them a great material for the chemical industry.

• Used as a material for industrial furnaces due to its ability to maintain its hardness at high temperatures.

• Used for making parts for CVD, ion implants, photolithography, and semiconductor parts.

• In traditional industries, alumina ceramics plate are good for products such as equiment parts, laser part, welding part, molding parts etc
