4. Thermal conductivity
Recrystallized silicon carbide (ReSiC) was the first advanced silicon carbide material to be used extensively for kiln furniture. ReSiC components are produced by firing a slip-cast green body formed from a mixture of various sizes of SiC particles at a temperature sufficiently high to cause vaporization of the finest particles. Upon cooling, the SiC vapor condenses and causes the large grains to be joined together (recrystallization). ReSiC is inherently porous and therefore more subject to oxidation. However, recent advances in re-firing, coating and doping processes have improved the performance of ReSiC so that it is still a viable choice in many applications, especially in the temperature range from 1350C up to its maximum use temperature of 1600C.
