Title: High Temperature Thermoelectric Properties of Yb₁₄MnSb₁₁ Prepared from Reaction of MnSb with the Elements

Abstract

Compounds of the Yb₁₄MnSb₁₁ structure type are the highest efficiency bulk p-type materials for high temperature thermoelectric applications, with reported figures of merit (ZTs) as high as ~1.3 at 1275 K. Further optimization of ZT for this structure type is possible with the development of a simple synthetic route. However, this has been difficult to achieve because of the small amount of Mn required compared with Yb and Sb. A simple synthetic route for Yb₁₄MnSb₁₁ has been developed utilizing a combination of ball milling and annealing to produce phase-pure material followed by spark plasma sintering for consolidation. The materials have been characterized by powder X-ray diffraction before and after spark plasma sintering. The stoichiometric reaction of Yb, Sb, and MnSb provides phase-pure powder by X-ray diffraction. Upon cycling to temperatures greater than 1272 K, Yb₁₄MnSb₁₁ shows the presence of Yb₁₁Sb₁₀. Additional samples with 5% and 10% excess Mn were also investigated. Adding 5–10% excess Mn does not change the low temperature properties and improves the high temperature ZT, resulting in a ZT of 1.1–1.2 at 1000 K for Yb₁₄Mn_1.05Sb₁₁, 30–40% improvement over that of the Sn flux reaction. The increase in ZT is attributed to optimization of the carrier concentration.more »« less

Earth Abundant High Temperature Materials for Radioisotope Power Conversion System

Technical Report Kauzlarich, Susan Mary ; Bux, Sabah K

Advances in high temperature thermoelectric materials were made and published. Two major developments are out lined in this final report. Alkaline earth Zintl phases represent the starting point of a series of compounds selected for development due to their high abundance as the supply chain and as the availability of certain rare earths (i.e. Yb) are limited and can be difficult to obtain. A new Zintl phase, Ca₁₄MnSb_11-xSn_x, where Sb is replaced by Sn resulting in changes to the band structure and properties. The structures are investigated by powder diffraction and samples consolidated into fully dense pellets for thermoelectric measurements. The band structure of a reasonable structure, Ca₁₄MgSb₇Sn₄, is calculated in order to better understand the properties. These Sn containing phases show improved thermoelectric properties over Ca₁₄MgSb₁₁ by increasing the Seebeck while decreasing resistivity without significant impact to the already low thermal conductivity. In addition, a composite phase of Yb₁₄MgSb₁₁ was investigated. Composite phases have been shown to improve both the thermoelectric efficiency and mechanical properties of materials. Here we demonstrate an improved thermoelectric figure of merit, power factor, and mechanical properties for the high-temperature p-type Zintl phase Yb₁₄MgSb₁₁. Composites with 0, 1, 2, 3, 4, 6, 8 volume % 6 – 10 µm reduced Fe powder were prepared via a fast, scalable mechanical milling and spark plasma sintering procedure. Powder X-ray diffraction, scanning electron microscopy, and transmission electron microscopy show that Fe is not incorporated into the Yb₁₄MgSb₁₁ structure. First order reversal curves and scanning electron microscopy images show that the Fe inclusions are larger and closer together with increasing Fe content. Thermogravimetric and differential scanning calorimetry show that the composites are stable up to 1273 K. The elastic constants of the 8 volume % Fe composite were measured by resonant ultrasound spectroscopy and show that Yb₁₄MgSb₁₁ becomes stiffer with increasing Fe volume % and SEM after indentations show crack arresting occurs at the Fe interface. Thermoelectric properties on dense pellets are measured from 300 K – 1273 K. The thermoelectric power factor (PF=more »« less
Magnetic and structural effects of partial Ce substitution in Y b{sub 14}MnSb{sub 11}

Single crystals of Y b{sub 14−x}Ce{sub x}MnSb{sub 11} were grown from tin metal as a flux solvent with a maximum Ce incorporation of 0.6. The phases with x ∼ 0.1–0.6 crystallize in the tetragonal Ca{sub 14}AlSb{sub 11} structure type with I4{sub 1}/acd space group. In this structure type, there are 4 crystallographically unique Yb sites and the structure can be described according to the Zintl concept as containing 14Y b{sup 2+} + [MnSb{sub 4}]{sup 9−} + [Sb{sub 3}]{sup 7−} + 4Sb{sup 3−}.

The compounds, Yb{sub 14−x}Tm{sub x}MnSb{sub 11} (0<0.5), were synthesized as single crystals via Sn flux. The maximum amount of Tm was determined from wavelength dispersive microprobe analysis to be x=0.45 (1).

Rare-earth transition metal compounds Yb{sub 14}MnSb{sub 11} and Yb{sub 14}MnBi{sub 11} have been prepared by heating stoichiometric amounts of the elements at 1000--1200 C. These compounds are isostructural with the Zintl compound Ca{sub 14}AlSb{sub 11} and crystallize in the tetragonal space group I4{sub 1}/acd (Z = 8). Single-crystal X-ray data (143 K) were refined for Yb{sub 14}MnSb{sub 11}. Structural analysis is consistent with Yb{sup 2+}. Temperature-dependent magnetic susceptibility data show that Yb{sub 14}MnSb{sub 11} orders ferromagnetically at 56 K and Yb{sub 14}MnBi{sub 11} has a ferromagnetic transition at 58 K and another transition at 28 K.
