Pure zirconium oxide nanocrystalline particles of the size range 6-140 nm in diameter are fabricated from ultrafine metallo-organic complexes by thermal hydrolysis at 120°C and heat treatment at 125 to 1025°C. X-ray powder diffraction for nearly monodispersed nanocrystallites reveals that the critical size of the ferroelastic transition between the tetragonal and monoclinic phases is around 25 nm in diameter. The critical size from the cubic to the tetragonal is strongly suggested to be 5 nm in diameter by X-ray photoelectron spectroscopy.
