摘要：

Dense bodies (>96% theoretical density) of Bi2O3Y2O3 oxygen ion conductor in the compositional range 50-85 mol% Bi2O3 were prepared. The activities of Bi2O3 in this system were measured using a solid electrolyte galvanic cell. The results show that the activity of Bi2O3 with 70 mol% Bi2O3 at 871 K is 0.084, and the equilibrium oxygen partial pressures are 10-15 to 10-16 atm, which are one or two orders of magnitude lower than that of pure Bi2O3 at the corresponding temperature. © 1992.
