Thermal conductivity is measured on Al2O3 ceramic, structural material SiC and high thermal conductivity SiC (2wt% BeO addition) ceramics at a temperature range of 2 to 300K. On the conductivity, these ceramics possess maxima, which are 0.9Wcm-1⋅K-1 at -80K for Al2O3; 4Wcm-1⋅K-1 at -100K for high thermal conductivity SiC; and 0.65Wcm-1⋅K-1 at -150K for structural material SiC.
