The effects of fabrication process parameters of P-Bi₂Te₃ on the thermoelectric properties has been studied. The factors are reduction of the powder from the ingot, cold isostatic press and sintering atmospheres of Ar and Ar/7%H₂. The size of pow-der less than 355μm was used. As one of results, the lowest electrical resistivity were obtained in the process of using a reduced powder and sintering in the atmosphere of Ar/7%H₂, which value at 57°C was 0.8×10^-4Ω⋅m as compared to 1.1×10^-4Ω⋅m sintered in the Ar atmosphere. Secondly, the results suggested that the tex-ture in the microstructure was important rather than density itself. The Seebeck coefficients of the specimens at 57°C sintered in Ar/7%H₂ using a reduced powder showed almost same value of 240μ⋅V/K as the normal powder specimens sinterd in Ar atmosphere. It is concluded that a reducing process positively is not necessarily effective for improving the thermoelectrical properties.
