skutterudites were synthesized, and their thermoelectric properties were studied by varying the filling ratio and charge compensation. X-ray diffraction analysis revealed that the matrix phase was skutterudite and a secondary phase was determined to the marcasite FeSb

. However, the formation of marcasite could be inhibited.....

DOI:
https://doi.org/10.3365/KJMM.2019.57.12.801
Abstract
Partially double-filled skutterudites were prepared via encapsulated melting and hot pressing processes. The skutterudite phase was successfully synthesized through partial double filling of La/Yb and substitution of Co. A small quantity of secondary phase (marcasite FeSb
2
) was formed, but its formation was suppressed by increasing Co charge compensation. The marcasite.....

Abstract
p-Type (La1−zNdz)0.8Fe4−xCoxSb12 skutterudites were prepared by partial double filling with La/Nd and charge compensation by substituting Co for Fe. The skutterudite phase was successfully synthesized using encapsulated melting, quenching, annealing and hot-pressing processes, but a small amount of the marcasite phase was identified. Partial filling within the filling fraction limit.....

Abstract
P-type Ce/Yb-filled skutterudites were synthesized, and their charge transport and thermoelectric properties were investigated with partial double filling and charge compensation. In the case of (Ce1-zYbz)0.8Fe4Sb12 without Co substitution, the marcasite (FeSb2) phase formed alongside the skutterudite phase, but the generation of the marcasite phase was inhibited by increasing Co.....
