Doped and partially-reduced oxide (e.g., SrTiO 3 -based) thermoelectric materials. The thermoelectric materials can be single-doped or multi-doped (e.g., co-doped) and display a thermoelectric figure of merit (ZT) of 0.2 or higher at 1050K. Methods of forming the thermoelectric materials involve combining and reacting suitable raw materials and heating them in a graphite environment to at least partially reduce the resulting oxide. Optionally, a reducing agent such as titanium carbide can be incorporated into the starting materials prior to the reducing step in graphite. The reaction product can be sintered to form a dense thermoelectric material. |
