The Influence of RuO2 Addition on the Thermoelectric Properties of BiSbTe Alloys

摘要：

　　P-type BiSbTe/RuO2 composite was fabricated using a combined process of melting and spark plasma sintering.The XRD patterns showed that RuO2 have reacted with the BiSbTe for the samples with 1.0 wt% and 4.0 wt% RuO2.The measured thermoelectric properties showed that the highest electrical conductivity was obtained for the sample with 2.0 wt% RuO2.The power factor (α2σ) decreased with the increase of RuO2 below 450 K.The lattice thermal conductivity was lower than that of BiSbTe over the whole temperature range for BiSbTe/2.0 wt% RuO2.
