The thermoelectric properties were examined of SiC specimens prepared by mixing α-SiC powder with B<SUB>4</SUB>C, C, and Al<SUB>2</SUB>O<SUB>3</SUB> and then sintering at 2100°C. Sintered specimens containing Al<SUB>2</SUB>O<SUB>3</SUB> up to 3% with 0.5% B<SUB>4</SUB>C and 2.5% C exhibited the highest densities. The electrical conductivities of these specimens increased with the Al<SUB>2</SUB>O<SUB>3</SUB> content up to 3%. In contrast, the Seebeck coefficients of these specimens decreased with the addition of 1% Al<SUB>2</SUB>O<SUB>3</SUB>, but then barely decreased with the further addition of Al<SUB>2</SUB>O<SUB>3</SUB>. The maximum value of the power factor, 9.43×10<SUP>−4</SUP> W/mK<SUP>2</SUP> at 800°C, was obtained with specimens sintered with 3% Al<SUB>2</SUB>O<SUB>3</SUB> as well as B<SUB>4</SUB>C and C. These results showed that the power factor of SiC ceramics could be enhanced by adding proper amounts of B<SUB>4</SUB>C, C, and Al<SUB>2</SUB>O<SUB>3</SUB> into them.
