Abstract

The monoclinic silicates Lu2SiO5 and Sc 2SiO5 (Y2SiO5 type, space groupC2/c) forma solid solution Lu2-xScxSiO5. Samples with x = 0.5, 0.8, 1.0 were synthesized ceramically from Lu2O 3, Sc2O3, and SiO2. The structures of three crystals with x = 0.88, 0.77, and 0.50 were refined on the basis of single-crystal X-ray diffraction data. The rare earth (RE) atoms occupy two crystallographically different 8 f sites with oxygen coordination numbers (CN) of 6 (RE2) and 7 (RE1). Refinements of the occupancy parameters showed Lu/Sc mixing for both sites with a strong preference of the smaller scandium atoms for CN6.
