Effect of γ-Al2O3 Content on the Thermoelectric Performance of ZrNiSn/γ-Al2O3 Composites
Year: 2003
Type: article
Abstract: . ZrNiSn matrix composites containing -Al2O3 nano particles with a relative density of 98 % were prepared by spark plasma sintering technique. Thermal conductivity, Seebeck coefficient, electrical resistivity were measured. It was shown that the addition of small amount of -Al2O3, which served as the additional phonon-scattering centers, led to a relative great reduction in thermal conductivity without significantly affecting the power factor. The dimensionless figure of merit ZT of ZrNiSn half-Heusler thermoelectric material was improved by introducing -Al2O3 nano particles.
