Half-Heusler (HH) alloys have recently gained a great deal of interest and attention for possible use as thermoelectric materials at higher temperature ranges, and HH TiNiSn is one of the most promising due to their combination of excellent thermal stability together with apparent similarities to some common semiconductor electrical behaviours[1]. This review will provide a thorough discussion of the synthesis and densification methods that have been applied to produce HH TiNiSn materials to date and their potential thermoelectric performance. Based on a systematic examination of the processing parameters discussed in nationally recognised institutions, as well as other laboratory studies, the figure of merit (ZT) of an HH alloy depend on optimising each of the properties in a manner where they are intertwined rather than simply trying to maximise the highest independent property value [1]. This review pays particular attention to how density, defect chemistry and the presence of secondary phases play a role in determining the thermal conductivity, electrical resistivity and Seebeck coefficient behavior of TiNiSn alloys when they are subjected to elevated temperatures (600-800 K). The discussion of the direction of future research will also focus on the need for quantitative phase analysis.
