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.
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.
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。
