چکیده انگلیسی
Bi85Sb15−xPrx (x=0,1,2,3x=0,1,2,3) alloys with partial substitution of Pr for Sb were synthesized by mechanical alloying followed by high-pressure sintering. The crystal structure was characterized by X-ray diffraction. The electrical conductivity and Seebeck coefficient were measured in the temperature range of 80–300 K. The results show that the electrical conductivity and Seebeck coefficient of Pr-substituted samples are both larger than those of the reference sample, Bi85Sb15, in the whole measurement temperature range. The power factor of Bi85Sb13Pr2 reaches a maximum value of 3.83×10−3 W K−2 m−1 at 235 K, which is about four times larger than that of the reference sample, Bi85Sb15, at the same temperature.
