| Abstract: | The present paper investigated the effect of 16 kinds of rare earth oxides and sintering process on the densities and thermal conductivity of BeO ceramic. Results show that the thermal conductivity of the samples added with Tb4O7 is highest, about 288 W/（m·k） and 295. W/（m·k）. CeO2, Nd2O3 can enhance the density of ceramics, reached 2. 939 g/cm^3 and 2. 927 g/cm^3 when sintering at 1630℃. |
