Abstract

New bismuth yttrium gadolinium oxide, Bi1.8Y0.1Gd0.1O3, synthesized from a stoichiometric mixture of Bi2O3, Y2O3, and Gd2O3, was characterized by X-ray powder diffraction. The compound was determined to be tetragonal, with space group P421c (114), unit-cell parameters of a=7.793 08(29) and c=5.665 71(40) Å, and the number of formulas per unit cell Z=4. Bi1.8Y0.1Gd0.1O3 is isostructural with β-Bi2O3.
