摘要: Abstract This paper gives an outline of the structure a solid solution based on 7Bi2O3 · 2WO3. The experimental results using X-ray diffraction methods (precession and powder) showed that 2WO3 crystallizes in space group I4 1 with = 12.5143(5)A c 11.2248(6) A. number formula weights per unit cell is 40, when considered to be oxygen-deficient fluorite-type Bi0.875W0.125O1.6875. compound has substructure defect pseudocubic subcell a′ ⋍ 5.6 axial relations between supercell are √a′ 2a′ . was formed over limited range WO3 content 21.3 mole% 26.3 at 700°C. ordering metal atoms discussed ideal crystal proposed.
