黑碳化硅P800# Black SiC Powder 的特點(diǎn)和用途


      黑碳化硅P800#是一種經(jīng)過氣流磨和水洗溢流工藝生產(chǎn)處理的碳化硅微粉。它不僅可以作為陶瓷、合金制品的研磨介質(zhì)，也可以用于生產(chǎn)碳化硅功能陶瓷。黑碳化硅本身具有很高的硬度、耐磨度、耐高溫、耐腐蝕性能，經(jīng)過酸堿化學(xué)處理、水洗后，鐵雜質(zhì)和游離碳含量更低，可以滿足更高端的需求。

Black silicon carbide P800 is a type of silicon carbide micro powder produced and treated by airflow grinding and water washing overflow process. It can not only be used as a grinding medium for ceramics and alloy products, but also for the production of silicon carbide functional ceramics. Black silicon carbide itself has high hardness, wear resistance, high temperature resistance, and corrosion resistance. After acid alkali chemical treatment and water washing, the content of iron impurities and free carbon is lower, which can meet higher end needs.
