“…The result on TiCoSb is smaller than those reported in the literatures. 20,24,28) For example, our measured value is À150 mV/K at about 350 K, while all the past reports show above À150 mV/K at 300 K. The results on ZrCoSb and HfCoSb are close to the literature data reported by Xia et al 31) and Melnyk et al, 30) respectively. The power factor given by S 2 = is shown in Fig.…”

“…Each lattice parameter of TiCoSb, ZrCoSb, and HfCoSb is 0.58845, 0.60648, and 0.60411 nm, respectively, which almost agree with the literature data of TiCoSb, 1,2,8,[18][19][20][21] and ZrCoSb and HfCoSb. 3,30) We detected the impurity phases on TiCoSb 28) and HfCoSb but not for ZrCoSb from the surface observation by SEM. We show the FE-SEM photograph of the surface of TiCoSb in Fig.…”

Thermoelectric Properties of (Ti,Zr,Hf)CoSb Type Half-Heusler Compounds

Half-Heusler compounds have a possibility as a new thermoelectric material due to the large thermoelectric power and low thermal conductivity derived from the band structure and voids in the crystal, respectively. Among these materials, we have paid attention to (Ti,Zr,Hf)CoSb system, and have investigated the improvement of the thermoelectric figure of merit from the measurements of the electrical resistivity, thermoelectric power, and thermal conductivity. We obtained the largest ZT ¼ 0:027 on TiCoSb at 921 K. From the analysis by Jonker plot and the difference of the atomic radii between titanium and cobalt on TiCoSb, it is indicated that the dispersion between our data and a few previous data was originated in two effects: one is deviations from the stoichiometric composition by evaporation of antimony on arc melting, and the other is relaxation of the structural disorder by annealing.

“…Obviously, the conductivity decreases with increasing temperature pointing towards a metallic character. [14] and three orders of magnitude lower than for ZrNiSb [15]. In the Supporting Information (available online; see note at the end of the paper for availability) the total electrical conductivities of Zr 3 T Sb 7 (T = Ni, Pd) are stated.…”

Herein we report on the syntheses, crystal structures and first electrochemical characterizations of ternary zirconium transition metal (poly)antimonides Zr 2 T Sb 3 (with T = Cu, Pd) and Zr 3 T Sb 7 (with T = Ni, Pd). The compounds were synthesized by arc-melting, followed by an annealing procedure at elevated temperatures. Phase analysis and structure analysis were performed by powder and singlecrystal measurements. The electrochemical properties of all compounds were measured in half cells against lithium to test their potential as anode materials for Li batteries. The Zr 3 T Sb 7 phases show metallic behavior with conductivities of 10 −1 S cm −1 within a temperature range of 324 to 428 K.

Hexagonal compounds of formula Zr 6 FeX 2 were prepared and studied by X-ray and neutron diffraction and by 57 Fe Mössbauer spectroscopy. The first results indicate that most of the compounds can be prepared mainly as a single phase after at least 5 weeks of annealing at a temperature close to 900• C. In particular, the hyperfine parameter distributions in Mössbauer spectra reflect the ability to form pure phases.
