Electrical and catalytic properties of some oxides with the fluorite or pyrochlore structure: Part 2: Catalytic oxidation of carbon monoxide [PDF]
, 1984 The catalytic properties of mixed oxides with the fluorite or pyrochlore structure were investigated using CO oxidation. The presence of ions with a variable valence state, the size of the ions and especially the extent of pyrochlore ordering affect ...

Dual‐Phase In Situ Symbiosis Structures for Ultrahigh Capacitive Energy Storage
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A dual‐phase in situ symbiosis structure designed by introducing a linear‐like pyrochlore phase (P phase) into the ferroelectric Aurivillius phase (A phase) and precisely controlling its proportion provides a new strategy for optimizing dielectric energy storage.

Synthesis, structure and electrical properties of Mg-, Ni-codoped bismuth niobates
Chimica Techno Acta, 2017 Mg-, Ni-codoped bismuth niobates Bi1.6Mg0.8-xNixNb1.6O7-δ (x = 0; 0.2; 0.4; 0.6; 0.8) were obtained by conventional solid-state reaction method. It was shown that the Mg atoms are distributed at the Nb sites while the Ni atoms are distributed over the Bi-

Hydrothermal synthesis of perovskite and pyrochlore powders of potassium tantalate [PDF]
, 2002 Potassium tantalate powders were hydrothermally synthesized at 100 to 200 °C in 4 to 15 M aqueous KOH solutions. A defect pyrochlore, Kta_(2)O_(5)(OH). nH2O (n ≈ 1.4), was obtained at 4 M KOH, but at 7–12 M KOH, this pyrochlore was gradually replaced by ...

Competing phases and topological excitations of spin-one pyrochlore antiferromagnets
, 2017 Most works on pyrochlore magnets deal with the interacting spin-1/2 local moments. We here study the spin-one local moments on the pyrochlore lattice, and propose a generic interacting spin model on a pyrochlore lattice.
