摘要：
Colorless plates of Zr50Sc12O118 have been produced by firing zirconia with scandia at temperatures above 1000 C and cooling slowly. The resulting crystals were heavily twinned. The unit cell is rhombohedral with space group R (3) over bar and lattice constants a = 1981.70(5) and c = 1805.59(6) pm. The structure is fluorite-related anion-deficient. Within the cell there are 18 vacancies on oxygen positions. A further neutron time of flight study revealed an almost statistical distribution of Zr and Sc on the cation positions.
