Effect of Sintering Temperature on Thermoelectric Properties of p‐Bi 2 Te 3 Alloys Produced by Gas Atomization
Source abstract
Abstract
In this research, p‐type Bi 2 Te 3 –75% Sb 2 Te 3 thermoelectric alloy powders were produced by gas atomization and subsequently sintered by hot pressing at different temperatures. The grain growth of the hot‐pressed samples was observed with increasing sintering temperature from 380°C to 460°C. The compressive strength increased with increasing hot‐pressing temperature due to the high relative density of bulk samples obtained at high temperatures. The effect of sintering temperature on thermoelectric (TE) properties was studied. The maximum power factor 3.48 mW/mK 2 was obtained for the sample hot pressed at 420°C due to the resulting high electrical conductivity and enhanced Seebeck coefficient values.
