Zr substituted bismuth uranate

Abstract

A Bi ₂ U _1–x Zr _x O _6–x solid solution has been evidenced for 0≤x≤0.40. The monoclinic Bi ₂ UO ₆ room-temperature form extends in the range 0≤x≤0.20 and the related trigonal high Bi ₂ UO ₆ form is stabilised at room temperature for higher substitution ratio. The electrical properties of these materials have been measured. Neutron diffraction combined with electron diffraction microscopy allow proposal of a structural model and confirmed the two dimensional properties of these materials.
