Structural and Thermoelectric Properties of Solid–Liquid In4Se3-In Composite
The aim of our work was to investigate thermoelectric properties of a composite of solid In 4 Se 3 and solid or liquid indium. Polycrystalline In 4 Se 3 -In composites were prepared by a direct reaction of elements, powdering of products and sintering powders by pulsed electric current sintering tec...

-In composites were prepared by a direct reaction of elements, powdering of products and sintering powders by pulsed electric current sintering technique. Microstructural and structural properties of obtained composites were analyzed using SEM + EDX and XRD techniques. Electrical transport properties and thermal conductivity were measured over a temperature range of 323 K ≤

≤ 673 K. Results show that the electrical conductivity of composite increases about four times in comparison with that of pristine In
