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.
主な機能:
1。高温酸化抵抗:
温度が1600 Cになると、酸化抵抗は非常に良好です。
2. High purity : made by chemical vapor deposition under high temperature chlorination condition.
3。侵食抵抗：高硬度、コンパクトな表面、微粒子。
4。耐食性：酸、アルカリ、塩、有機試薬。
