Hexoloy® SE SiC offers an excellent alternative material to metals, superalloys and other ceramics for applications such as chemical processing, high temperature furnaces, and other demanding, severe environment applications. Hexoloy SE SiC provides a full range of exceptional properties in one package including:
Hexoloy SE SiC is produced by pressureless sintering of submicron silicon carbide powder in a proprietary extruding process. The sintering process results in a self-bonded, fine grained (less than 10μm) SiC product which is 95% dense. Saint-Gobain can supply Hexoloy SE SiC extruded components to your specifications.
Hexoloy SiC is one of the hardest high performance materials available and is 50% harder than tungsten carbide. Its density is in excess of 95% of theoretical and it is completely impervious without the use of an impregnants, which means no contamination in high purity applications.
