Abstract: The preparation of fine powders of nanosized TiO2-ZrO2 composite oxides using hydrothermal method was investigated. ZrO2(C)-TiO2(A), ZrO2(C)-TiO2(R), ZrO2(T)-TiO2(A), ZrO2(T)-TiO2(R) nanosized composite-oxides and amorphous composite-hydrous oxides of Ti-Zr were obtained. Their transformation and stability were studied. The ZrTiO4 ceramic with theoretical density of 95% was obtained at 1400oC for 10h.

Key words: Zirconia, Titania, Zirconium titanate, composite oxides
