[en] Reaction in HfO₂-Y₂O₃-CaO and ZrO₂-Y₂O₃-CaO systems is studied. Isothermal cross sections of phase diagrams are plotted at 1600 and 1850 deg C. Ternary compounds are not formed within the investigated interval. Ranges of solid solutions on the basis of HfO₂, ZrO₂ monoclinic, cubic and tetragonal modifications, CaHfO₃ and CaZrO₃ rhombic form and CaO and Y₂O₃ C-form are determined
