The theoretical thermal conductivity of silicon carbide is very high, reaching 270W/m•K. However since the ratio of surface energy to interfacial energy of SiC ceramic materials is low, that is, the grain boundary energy is high, it is difficult to produce high purity and dense SiC ceramics by conventional sintering methods.

Silicon carbide (SiC) has high thermal conductivity. Because of the high surface area of Duocel® foam, heat transfer to/from fluids flowing through the foam is greatly accelerated. Duocel® silicon carbide foam is also ideal for use with phase change materials (PCM) because of the large amount of surface area, which increases coupling to PCM.
