Researchers are currently developing ways to produce thermoelectric materials, such as skutterudites, with low lattice thermal conductivity. In this paper, a hydrothermal synthesis procedure was developed to fabricate CoSb3 compounds. A thermal constant analyzer measured the thermal conductivity of three CoSb3 samples using the transient plane source (TPS) method. Results showed that thermal conductivity increased with decreasing temperature, and was much lower for the hydrothermal-synthesized CoSb3 samples than other fabrication ...
