Ceramic wafer polishing plate is a stage made of alumina ceramic materials. Alumina ceramics have excellent resistance to high temperature, wear and corrosion, so they are used as wafer bonding plates in polishing processes.

CHEMSHUN's alumina ceramic wafer polishing plates are usually made of high purity alumina ceramic powder by PIBM self-solidification process. Its main features include:

Excellent high temperature resistance: alumina ceramic plate can be used for a long time in high temperature environment.

Good wear resistance: alumina ceramic plate can be used in high-friction environments to reduce wear and debris generation.

Corrosion resistance: It can be used stably in acid and alkali polishing fluid environment for a long time.

High precision: with mature ceramic plate manufacturing process, can be customized according to customer requirements, high precision, can meet the requirements of different equipment include LED,SiC,Si...

Pingxiang Chemshun Ceramics' High Purity 99.7% Alumina Ceramic Sapphire Lapping wafer Polishing plate as an important component of CMP chemical mechanical polishing process.  CMP is the necessary for producing process of the sapphire and Wafer.  Because of the high purity alumina ceramics polishing plate excellent working performance, it is replacing the Metal wafer polishing plate.?
