Relationship between effective ionic radii, structure and electro-mechanical properties of zirconia stabilized with rare earth oxides M_20_3 (M = Yb, Y, Sm)

摘要

Zirconia stabilized with various concentrations of rare earth oxides of Yb, Sm and Y with different effective ionic radii ratio between the dopant and host cations was studied. In particular, structure, phase composition, compositional range for existence of cubic solid solutions and their phase transformations, stabilization degree of high-temperature phases and the crystal chemistry and type of solid solutions were investigated. These findings were related to the measured material characteristics, namely the electrical conductivity, microhardness
