ZrNiSn-based half-Heusler compounds were fabricated by the method of solid state reaction. In a Hf0.5Zr0.5Ni0.8Pd0.2- Sn0.99Sb0.01 compound, a thermal conductivity as low as 4.5 W/m-K was measured at room temperature. Although the Seebeck coefficient decreased, it was only by a small amount. The ZT value reached a maximum value of 0.7 at about 800 K for the Hf0.5Zr0.5Ni0.8Pd0.2- Sn0.99Sb0.01 sample.
