Compositions and methods for thermoelectric ceramics
In one aspect, the disclosure relates to thermoelectric ceramic oxide compositions comprising a CaMnO3 ceramic. In a further aspect, the disclosed thermoelectric ceramic oxide compositions can dramatically increase the energy conversion efficiency of thermoelectric through a combination of modifying the chemistry of precursor materials, and simultaneously introducing a metal oxide liquid phase during sintering. In a further aspect, the present disclosure pertains to thermoelectric ceramic oxide compositions comprising a metal doped CaMnO3 having with a metal oxide grain boundary phase; wherein the metal is selected from group 13, group 14, group 15, group 16, or a rare earth element. In a still further aspect, the disclosure relates to methods for making the thermoelectric ceramic oxide materials. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
