What Are the Ceramic Materials With High Thermal Conductivity?

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. Sintering AIDS must be added when conventional sintering methods
