| Research Abstract |
The thermoelectric oxides and their composites were synthesized and their microstructures were controlled by using the chemical solution process, resulting in enhancement of thermoelectric performance and establishment of synthesis process at lower temperature and for shorter period of operating time. Especially in the case of the n-type SrTiO_3, mixing with TiB_2 was found to be quite effective for enhancing thermoelectric performance due to reduction in electrical resistivity and decreasing temperature of sintering by about 200K. As a result, the total synthesis process from powder preparation to final sintering at lower temperature and for shorter period of operating time was established by using the chemical solution process.
