ABSTRACT:
A technique for forming from staring precursors at the molecular level, a sultant thermoelectric material with a reduced thermal conductivity. All staring precursors are dissolved in solution, reduced to remove oxygen, and then combined into a single solution to yield specific stoichiometric ratios. A sol and then a gel is formed, which supercritical solvent extraction is performed upon so as to yield a material having two level porosity and a maximum of a factor of three reduction in thermal conductivity.
