Recrystallized Silicon Carbide (ReSiC)

It was the first advanced SiC material to be used extensively for kiln furniture in the mid-1970s. Pioneered and currently marketed as Crystar® 2000 by Saint-Gobain /Norton, ReSiC is inherently porous. But thanks to its recrystallized microstructure that is developed through targeted firing at a very high temperature, it exhibits good oxidation resistance. Thus ReSiC is a viable choice in many applications especially in the temperature range from 1350°C up to its maximum use temperature of 1600°C.

Advanced Nitride Bonded Silicon carbide (NSiC)(2)

The composition of the green body includes silicon powder and the Si₃N₄ bond is formed in-situ by firing the body at high temperature in a nitrogen atmosphere. Pioneered and marketed as Advancer® by Saint-Gobain/Norton, NSiC has almost twice the strength of ReSiC.Our NSiC product line includes Advancer®, AnnaSicon®RT, andAnnaSicon® RTH to be selected according to the considered service condition.

Siliconized Silicon carbide (SiSiC)

Actually a reaction bonded silicon infiltrated SiC, developed and marketed by Saint-Gobain/Cesiwid as Silit® SK. The composition of the green body includes some carbon and the high temperature firing occurs in the presence of an excess of Si grains. As the molten Si diffuses through the body, it reacts with the carbon to form a â-SiC bond. The remaining open porosity is filled with the excess silicon, thus an outstanding oxidation resistance, but a service temperature limited to 1370°C due to the melting of the free silicon.

Sintered SiC (SSiC)

This fully dense SiC material, was formulated for applications requiring superior oxidation resistance with extremely high strength. Pioneered and marketed as HEXOLOY® SE by Saint-Gobain/Carborundum, SSiC beams have the highest strength and highest service temperature limit - 1650°C in air - of the four advanced SiC products.  More information on HEXOLOY® SE
