Abstract

The properties of zirconia solid solution powders were characterized with a series of ZrO₂-TiO₂-Y₂O₂ nanosized powders synthesized by chemical co-precipitation. XRD (X-Ray Diffraction) showed that powders were tetragonal solid solutions. The average particle size was 10-25 nm as determined by TEM (Transmission Electron Microscope) and BET specific surface area measurements. With increasing TiO₂ content, the lattice parameter a decreased while c increased and as a result c/a increased. The molar fraction x of TiO₂ in t-ZrO₂ was up to 40%. because of the surface effect in the nanosized powders. The ZrTiO₂ phase was observed in the ceramic materials after sintering for a solid solution x (TiO₂) content of 20%.
