ZrNiSn bulk thermoelectric materials were synthesized by a self-propagating high-temperature synthesis (SHS) process. Phases and microstructure of ZrNiSn were investigated. Its thermoelectric property was tested. The results show that there are a large number of nuclei and high concentration of dislocation groups and stress fluctuation area inside the dense material, greatly enhancing the phonon scattering and reducing the phonon mean free paths, thus leading to the decreased lattice thermal conductivity of the materials. The thermoelectric properties of the material were optimized, and the ZT value is 0.54 at 873 K.
