Abstract
The electrical conductivity of M2O3‐ZrO2 compositions containing 6 to 24 mole % M2O3, where M represents La, Sm, Y, Yb, or Sc, was examined. Only Sm2O3, Y2O3, and Yb2O3 formed cubic solid solutions with ZrO2 over most of this substitutional range. Scandia forms a wide cubic solid solution region with ZrO2 at temperatures above 130°C whereas the cubic solid solution region at room temperature is narrow (6 to 8 mole % Sc2O3). Lanthana additions to ZrO2produced no fluorite‐type cubic solid solutions within the compositional range investigated. Generally, the electrical conductivity of these cubic solid solutions increased as the size of the substituted cation decreased and the electrical conductivity for each binary system attained a maximum at about 10 to 12 mole % M2O3.
