A structural and microstructural study was performed on several compositions of the Smy(FexNi1-x)4Sb12 system treated at three different pressures during the spark plasma sintering (SPS) process. Aim of the study is to recognize the effect of applied pressure at a fixed temperature on composition, microstrain and domains size, due to the...

Filled skutterudites are currently studied as thermoelectric materials to be used in the automotive and nautical field; the study of their resistance to a saline environment is therefore mandatory. To this purpose, the corrosion behavior of several compositions belonging to the Smy(FexNi1−x)4Sb12skutterudites system was investigated by...

Filled skutterudite compounds Smy(Fe1−xNix)4Sb12 (nominal composition 0 ⩽ x ⩽ 0.56, 0.1 ⩽ y ⩽ 1.2) were synthesized under high pressure using a cubic anvil press. The samples were characterized by X-ray diffraction, scanning electron microscopy with energy-dispersive X-ray spectrometry and electron probe microanalyzer. Thermoelectric properties...

The effect of varying the applied pressure during the processing by spark plasma sintering (SPS) of samples belonging to the Smy(FexNi1-x)4Sb12 system has been investigated by evaluating the power factor of the obtained filled skutterudite. A strong dependence of both the electrical conductivity and the Seebeck coefficient on the applied...

The crystallographic and transport properties of thin films fabricated by pulsed laser deposition and belonging to the Sm- y (Fe x Ni1-x )(4)Sb-12 filled skutterudite system were studied with the aim to unveil the effect exerted by temperature and duration of thermal treatments on structural and thermoelectric features. The importance of...
