Abstract
The quadrivalent oxidation stage of the elements praseodymium and terbium can be easily prepared as oxides BaPrO/sub 3/ and BaTbO/sub 3/ crystallizing with the Perovskite structure. From this observation one has tried to stabilize the elements neodymium and dysprosium in the lanthanide series by including a host lattice with Perovskite structure. BaCeO/sub 3/, BaPrO/sub 3/, BaZrO/sub 3/, BaThO/sub 3/, BaTbO/sub 3/, SrCeO/sub 3/ and SrTbO/sub 3/ are used as host lattices. The preparation was carried out by simple annealing of the corresponding oxides with BaCO/sub 3/ or SrCO/sub 3/ in air at 1350/sup 0/C. X-ray and analytical characterization showed that Nd(IV) and Dy(IV) were partly taken up by a few host lattices.
