Summary:The change in physicochemical properties of nanocrystalline powder of the composition ZrO^sub 2^ -- 3 mole% Y^sub 2^O^sub 3^ in the presence of aluminum fluoride is studied. The starting powder is prepared by a complex method including elements of hydrothermal synthesis and sol-gel technology. It is established that these conditions expand the temperature limits for the existence of ZrO^sub 2^ monoclinic solid solution. Transformation is connected with adsorption of fluorine at the ZrO^sub 2^ surface, diffusion in the solid phase, and a reduction in anion vacancy concentration.[PUBLICATION ABSTRACT]
