In the present experimental study, the precipitation of basic yttrium nitrate from aqueous solutions allowed the optimization of conditions for the preparation of loosely aggregated Y$_{2}$(OH)$_{5}$NO$_{3}$ $\cdot$ 1.5H$_{2}$O, the thermal decomposition of which, under controlled annealing, permitted the synthesis of yttria nanoparticles with desirable microstructure. The latter material can be widely used to manufacture yttria optical ceramics. Y$_{2}$(OH)$_{5}$NO$_{3}$ $\cdot$ 1.5H$_{2}$O thermolysis occurs via the formation of a metastable hexagonal Y$_{2}$O$_{3}$ based phase (a = 8.04, c = 12.37 $\mathring{\mathrm{A}}$).
Keywords: yttrium oxide, optical ceramics, X-ray diffraction phase analysis.
