A similar topology was found for the ZrO2-Y2O3-CeO2 and HfO2-Y2O3-CeO2 phase diagrams as a consecuence of the similar crystal structures of zirconia and hafnia. Conditions of the derivation of metastable tetragonal phase on the basis of zirconium and hafnium oxides in above-stated ternary systems are investigated.
