文摘
- •
The effect of Sb doping on thermoelectric properties of post spark plasma sintering annealed SnO2 ceramic was studied.
- •
Addition of Sb greatly affects the microstructure and thermoelectric properties of SnO2.
- •
Thermal conductivity of the Sb doped samples decreases with increasing Sb content.
- •
The highest thermoelectric figure of merit of ZT ≈ 0.06 at 1073 K was exhibited by the sample of composition Sn0.99Sb0.01O2.
