Abstract Y$_{2}$O$_{3}$ nanopowders were synthesized using a chemical precipitation
process from coarse yttira Y$_{2}$O$_{3}$ powders, ammonium hydro--carbonate,
nitric acid and aqueous ammonia. X--ray diffraction (XRD) was used to determine
the phase constitution of the yttria powder. Morphology and size of the powders
were observed by transmission electron microscope(TEM). Size distribution of the
powder was analyzed using Image Analyser. The precipitation
processing parameters and calcination temperatures have a significant effect on
the particle size and size distribution of the synthesized Y$_{2}$O$_{3}$ nanopowder,
and thus influence the density and transparency of the sintered ceramics.
The Y$_{2}$O$_{3}$ nanopowder produced by calcining the precursor (obtained at
a pH of 8) at 1000℃ is 30 nm in particle diameter, spherical in shape, well
dispersed, and narrow in size distribution. This Y$_{2}$O$_{3}$ powder can be
sintered into transparent body by a vacuum sintering at 1700℃ for 4 h
without any additive.
