Semicera Energy Technology Co., Ltd.is a leading supplier of advanced semiconductor ceramics and the only manufacturer in China that can simultaneously provide high-purity silicon carbide ceramic(especially theRecrystallizedSiC) and CVD SiC coating. In addition, our company is also committed to ceramic fields such as alumina, aluminum nitride, zirconia, and silicon nitride, etc.
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. Resistenza all'ossidazione ad alta temperatura:
La resistenza all'ossidazione è ancora molto buona quando la temperatura è alta fino al 1600 C.
2. High purity : made by chemical vapor deposition under high temperature chlorination condition.
3. Resistenza all'erosione: alta durezza, superficie compatta, particelle fini.
4. Resistenza alla corrosione: acido, alcali, sale e reagenti organici.
