Hexoloy® SiC oxidation and creep resistant, low mass, high strength and temperature SiC refractory material increases throughput and lowers cost of kiln operation.
High Temperature Hexoloy SiC
Oxidation resistant material such as Hexoloy SiC (Silicon Carbide) is used in many industrial applications. Hexoloy SiC specifically is an ideal choice for high temperature environments.
When exposed to 1100″C steam for extended periods, Hexoloy SiC demonstrates superior oxidation resistance compared to Siliconized SiC, Nitride Bonded SiC and Recrystalized SiC. In a test running in excess of 500 hours, Hexoloy SiC outperformed other SiC formulations, as indicated by very low percent weight gain.

Oxidation Resistant Hexoloy SiC Kiln Support Beams
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.
Kiln Support Beams made from Hexoloy SiC have several advantages including low mass design potential, high strength, creep resistance and oxidation resistance. Hexoloy SiC beams are a cost effective solution for high temperature demanding kiln applications. Advantages include:
Creep Resistant Material
Creep resistant materials avoid the tendency to move or deform permanently under the influence of stress. Creep takes place over time and results from long-term exposure to stress levels below a material’s yield strength. Creep is more severe in materials subjected to heat for long periods at levels close to the materials melting point. For example, a turbine blade made of a non-creep resistant material and used in a high temperature environment, may creep over time, contact the housing and damage the blade.
Creep resistant materials play a critical role in many applications including:
Component failure is often the result of creep. Other everyday creep resistant material applications include the use of these materials in the production of spark plugs.
Saint-Gobain creep resistant technical ceramic materials are used in many kiln related applications.
