摘要：

Metastable phase relationship in the ZrO2-YO1.5, ZrO2-TiO2 and YO1.5-TiO2 systems has been investigated using precursors prepared by a sol-gel method through metal alkoxides. Well-crystallized phases were formed by heating the precursors at and above 1073 K for 10 h. Extended solubilities were obtained in the tetragonal zirconia, cubic fluorite, YO1.5, ZrTiO4, and Y2Ti2O7 solid solution by heat treatments at 1073 and 1273 K. Although the equilibrium Y2Ti2O7 phase did not appear, a metastable cubic phase was obtained by heating Y1-xTixO1.5+x/2 (x=0.29 and 0.38) at 1073 K.
