Abstract: A new compound with the filled-skutterudite structure, Ba x Pd4Sn y Sb12−y , was prepared by the flux growth and spark plasma sintering (SPS) techniques. The crystal structure was determined from single crystal and powder x-ray diffraction data. The structure is electronically stabilized by the Sn:Sb ratio, and the lattice parameters depend on this ratio. For magnetic, electrical conductivity, Hall coefficient, Seebeck coefficient and thermal conductivity measurements, single crystal and/or SPS-densified specimens were utilized. Ba1.0Pd4Sn7.1Sb5.2 exhibits diamagnetic behavior. The Hall coefficient is negative and increases with temperature. The lattice thermal conductivity of Ba0.97Pd4Sn6.90Sb4.97 (SPS-densified) is smaller than for CoSb3, but the thermoelectric figure of merit (ZT) is comparatively low due to the low Seebeck coefficient.
