Hexagonal manganates RMnO 3 (R=Y, Ho, Dy) have been recently shown to exhibit oxygen-storage capacities promising for three-way catalysts, air-separation, and related technologies. Here, we demonstrate that Ti substitution for Mn can be used to chemi

The perovskite, BiNb3O9, is a metastable phase in the Bi2O3:Nb2O5 system that forms only when cooled from a liquid phase. Crystals of BiNb3O9 prepared in this way display pseudocubic 2a×2a×2a diffraction patterns, due to non-merohedral twinning of

Bismuth-niobate-based ceramic materials are of interest for embedded elements such as capacitors and filters because they exhibit high relative dielectric permittivities and tend to be processible at temperatures in the 1000°–1200°C range. As par

The crystal structure of the phase previously reported to occur at 4:9 Bi2O3:Nb2O5 has been determined using single-crystal X-ray and powder neutron diffraction (P63/mmc; a=7.4363(1) A, c=19.7587(5) A; Z=2). The structural study combined with phase e

Phase equilibria studies of the CaO:TiO{sub 2}:Nb{sub 2}O{sub 5} system confirmed the formation of six ternary phases: pyrochlore (A{sub 2}B{sub 2}O{sub 6}O'), and five members of the (110) perovskite-slab series Ca{sub n}(Ti,Nb){sub n}O{sub 3n+2}, w

Subsolidus phase relations have been determined for the Bi–Co–Nb–O system in air (750–925 °C). Ternary compound formation was limited to pyrochlore (A2B2O6O′), which formed a substantial solid solution region at Bi-deficient stoichiometrie
