Preparation and thermopower of new mischmetal-based partially filled skutterudites MmyFe4−x(Co/Ni)xSb12

Thermoelectric properties of p-type didymium (DD) based skutterudites DDy(Fe1−xNix)4Sb12 (0.13⩽x⩽0.25, 0.46⩽y⩽0.68)

“…1a), obeying Vegard's law, as previously observed e.g. for Ce y Fe 4Àx Ni x Sb 12 [23][24][25]. The lattice parameters agree well with data for the end members DD 0.88 Fe 4 Sb 12 [8], DD 0.86 Fe 4 Sb 12 [8], Nd 0.72 Fe 4 Sb 12 [26], NdFe 4 Sb 12 [27], Pr 0.87 Fe 4 Sb 12 [28], PrFe 4 Sb 12 [29] and Fe 2 Ni 2 Sb 12 [27], as well as with those for hand milled (HM) DD y (Fe 1Àx Ni x ) 4 Sb 12 alloys [7].…”

A thermoelectric generator based on an n‐type clathrate and a p‐type skutterudite unicouple

“…p‐type Mm y Fe 4− x (Co/Ni) x Sb 12 skutterudites were first reported in Ref. and their TE properties at high temperature are reported in Ref. .…”

Thermoelectric performance of mischmetal skutterudites MmyFe4−xCoxSb12 at elevated temperatures

“…In addition, Mm multi-element filling in skutterudite is supposed to enhance phonon scattering. Although thermoelectric properties for Mm-filled skutterudites Mm y Fe 4−x T x Sb 12 (T is Co and Ni) have been measured at low temperatures [17][18][19][20], no investigations were carried out at high temperatures.…”
