Thermoelectric materials offer a great potential for directly converting heat into electricity and are essential for wide-scale renewable energy application. For efficient conversion high electrical conductivity and low thermal conductivity is desirable. In this work we investigate the influence of synthesis and annealing on transport properties and the thermoelectric figure of merit (ZT) of this material. We will describe experimental details and numerical results on thermal and electrical properties of bulk Fe2V0.8W0.2Al. Briefly, both electrical resistivity and thermal conductivity, and Seebeck coefficient are measured. The implication of our findings will be discussed.
