The basic sintered silicon carbide products contain no free silicone with excellent resistance to wearing and chemical attacks at oxidizing and deoxidizing conditions. It is widely used in hard tracking faces with excellent performance. In all kinds of chemical media, its resistance to chemical attacks is better than tungsten carbide, ceramics and reaction bonded silicon carbide, and it has longer life for sealing faces.
Meanwhile, for some special working conditions and applications, The sintered silicon carbide products can be used to tackle key problems and offer special solutions, such as high speed compressors, sealing key pumps in nuclear power stations, amour protections etc
