Abstract:
The crystal and local structures of compounds formed in the Dy2O3–HfO2 system (at molar ratios from 1: 3 to 3: 1) in the course of isothermal annealing of X-ray amorphous mixed hydroxides at temperatures up to 1600°C have been studied. At the molar ratio Dy2O3: HfO2 from 1: 3 to 1: 1, crystallization leads to formation of single-phase defect fluorite solid solutions nDy2O3 ∙ mHfO2 with clearly pronounced nonequivalence of parameters of local environment of Dy3+ and Hf4+ cations. It has been found that Dy2H2O7 (Dy2O3: HfO2 = 1: 2) samples have a tendency to pyrochlore-type ordering in both the cationic and anionic sublattices.
