Relationship between Thermoelectric Properties and Microstructure on p-Type (Bi2Te3)0.25(Sb2Te3)0.75 System Using Milled Powder

Year: 1996

Type: article

Abstract: Semiconducting ceramics of p-type bismuth telluride by hot pressing the milled powders of (Bi2Te3)0.25(Sb2Te3)0.75 particle size of 1.9μm and 0.29mass% impurity oxygen was fabricated. These ceramics showed a maximum figure of merit of 2.4×10-3K-1 at 25°C when the grain size was 5μm because their thermal conductivity apparently became the lowest possibly due to enhanced phonon scattering at grain boundaries. Their thermoelectric properties did not exhibit anisotropy due to their isotropic microstructure with no grain orientation.
