“…The radiation spectrum of thermophotovoltaic emitter has to be matched with the bandgap of the photovoltaic cell, which generally requires the emitter temperature to be at least 730 °C (1000 K) for practical power density and conversion efficiency. While thermoelectric devices have been used at room and moderate temperatures for refrigeration and waste heat recovery, there is continued push for high‐efficiency thermoelectric materials at high temperature, such as Si–Ge, half‐Heusler, and oxides, for applications in space exploration, high‐temperature waste heat harvesting (e.g., from industrial furnaces), and combustion‐ or solar‐driven generators 14a…”

High temperature processes are widely used in a variety of existing and emerging industrial and aerospace applications. The thermal properties of high‐temperature materials thus play an important role in controlling the thermal energy, as highlighted by successful applications of thermal barrier coating and aerogels. While thermal transport processes at room and low temperature have witnessed tremendous progress in the past two decades, particularly on the fronts of understanding basic heat transfer properties at the micro‐ and nanoscale, the understanding at high temperature is still at the nascent stage, owing to several unique features at high temperature, such as the dominant Umklapp scattering effect that can render a crystalline material amorphous‐like thermal properties, and the important radiation contribution at high temperature. This lack of systematic understanding, coupled with the challenges in maintaining high‐temperature stability in a large number of materials, has limited the development of materials to meet the thermal transport properties pertaining to several current and emerging high‐temperature applications. This Review is aimed at providing an overview of the basic mechanisms governing thermal transport processes at high temperature, to identify their unique features and challenges, and to explore opportunities in material research for high‐temperature thermal materials.

“…Thermoelectric materials show great potential application in the field of waste heat recovery, power generators and solid refrigeration due to their direct conversion between heat energy and electrical energy. The conversion efficiency of thermoelectric material is primarily governed by the dimensionless figure-of-merit, ZT = α 2 σT/(κ L + κ e )κ, where α, σ, α 2 σ, κ L , κ e and T are the Seebeck coefficient, electrical conductivity, power factor, lattice thermal conductivity and carrier thermal conductivity of total thermal conductivity κ and absolute temperature, respectively [1][2][3]. As the physical parameters α, σ, and κ e are coupled via effective mass (m*) and carrier concentration (n), it is a major challenge to improve the ZT by independently optimizing these parameters.…”

Abstract:The Ni-doped ZrCo 1−x Ni x Sb half-Heusler compounds were prepared by arc-melting and spark plasma sintering technology. X-ray diffraction analysis results showed that all samples were crystallized in a half-Heusler phase. Thermoelectric properties of ZrCo 1−x Ni x Sb compounds were measured from room temperature to 850 K. The electrical conductivity and the absolute value of Seebeck coefficient increased with the Ni-doping content increasing due to the Ni substitution at Co. sites. The lattice thermal conductivity of ZrCo 1−x Ni x Sb samples was depressed dramatically because of the acoustic phonon scattering and point defect scattering. The figure of merit of ZrCo 1−x Ni x Sb compounds was improved due to the decreased thermal conductivity and improved power factor. The maximum ZT value of 0.24 was achieved for ZrCo 0.92 Ni 0.08 Sb sample at 850 K.

“…The expected decrease of κ L due to the addition of nano-TiO 2 is not evident in other TiO 2 /Cu 2 SnSe 3 composites, which is possibly attributed to the distribution of nano-TiO 2 in the grain boundaries. However, the κ L of 1.4%TiO 2 Cu2SnSe3 sample, the lower κL of TiO2/Cu2SnSe3 sample in this study should be related with the distribution of TiO2. Figure 10 shows the temperature dependence of the dimensionless figure of merit ZT of TiO2/Cu2SnSe3 composites.…”

“…In the process of industrial production, most energy is released in the form of heat. Thermoelectric (TE) materials can directly convert waste heat into electricity based on the Seebeck effect [1,2]. While TE materials show a great prospect environmentally and economically, the lower efficiency of TE materials limits their wide application.…”

Thermoelectric (TE) materials are a kind of energy material which can directly convert waste heat into electricity based on TE effects. Ternary Cu 2 SnSe 3 material with diamond-like structure has become one of the potential TE materials due to its low thermal conductivity and adjustable electrical conductivity. In this study, the Cu 2 SnSe 3 powder was prepared by vacuum melting-quenching-annealing-grinding process. The nano-TiO 2 particles were introduced into the Cu 2 SnSe 3 matrix by ball milling. Spark plasma sintering (SPS) was employed to fabricate the TiO 2 /Cu 2 SnSe 3 composites. The X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and transmission electron microscopy (TEM) were used to study the phase and microstructure of TiO 2 /Cu 2 SnSe 3 composites. Electrical resistivity, Seebeck coefficient, and thermal conductivity measurement were applied to analyze the thermoelectric properties. For the 1.4%TiO 2 /Cu 2 SnSe 3 composite, the electrical conductivity was improved whereas the Seebeck coefficient was lower than that of pure Cu 2 SnSe 3 . For other TiO 2 /Cu 2 SnSe 3 samples, the Seebeck coefficient was improved while the electrical conductivity was reduced. The thermal conductivity of TiO 2 /Cu 2 SnSe 3 composites was lower than that of Cu 2 SnSe 3 matrix, which is attributed to the lower carrier conductivity. A maximum ZT of 0.30 at 700 K for the 1.0%TiO 2 /Cu 2 SnSe 3 composite was obtained, which was 17% higher than that of the pure Cu 2 SnSe 3 at 700 K.
