PSS processing carrier for semiconductor wafer transmission

Short Description:

Silicon carbide is a new type of ceramics with high cost performance and excellent material properties. Due to features like high strength and hardness, high temperature resistance, great thermal conductivity and chemical corrosion resistance, Silicon Carbide can almost withstand all chemical medium. Therefore, SiC are widely used in oil mining, chemical, machinery and airspace, even nuclear energy and the military have their special demands on SIC. Some normal application we can offer are seal rings for pump, valve and protective armor etc.

We are able to design and manufacture according to your specific dimensions with good quality and reasonable deliver time.

Product Description

Our company provides SiC coating process services by CVD method on the surface of graphite, ceramics and other materials, so that special gases containing carbon and silicon react at high temperature to obtain high purity SiC molecules, molecules deposited on the surface of the coated materials, forming SIC protective layer.

Main features:

1. High temperature oxidation resistance:

the oxidation resistance is still very good when the temperature is as high as 1600 C.

2. High purity : made by chemical vapor deposition under high temperature chlorination condition.

3. Erosion resistance: high hardness, compact surface, fine particles.

4. Corrosion resistance: acid, alkali, salt and organic reagents.
