文摘In this paper, the conductivities of BaPbO 3 and BaPbO 3-Nd 2O 3 system ceramics are studied. The experimental results show that the charge carriers in this system ceramics are donor electrons captured in oxygen vacancies. The conductivity and the PTC characteristics of the BaPbO 3-Nd 2O 3 ceramics are obviously different from those of pure BaPbO ceramics.
