黑碳化硅P800# Black SiC Powder 的特点和用途


      黑碳化硅P800#是一种经过气流磨和水洗溢流工艺生产处理的碳化硅微粉。它不仅可以作为陶瓷、合金制品的研磨介质，也可以用于生产碳化硅功能陶瓷。黑碳化硅本身具有很高的硬度、耐磨度、耐高温、耐腐蚀性能，经过酸碱化学处理、水洗后，铁杂质和游离碳含量更低，可以满足更高端的需求。

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.
