Electrical conductivity of Bi2O3-Tm2O3-Nb2O5 solid solutions
摘要:
New solid solutions, Bi2-x-yTmxNbyO3-delta, with tetragonal and cubic structures have been synthesized in the Bi2O3-Tm2O3-Nb2O5 system, and their electrical conductivity has been measured at temperatures from 670 to 1020 K. The 1020-K conductivity of the tetragonal solid solution Bi1.8Tm0.15Nb0.05O3+delta is comparable to that of Bi1.75Tm0.25O3, the best conductor in the Bi2O3-Tm2O3 system.
