Crystal structure of synthetic hafnon, HfSiO4, comparison with zircon and the actinide orthosilicates

Crystal structure of synthetic hafnon, HfSiO4, comparison with zircon and the actinide orthosilicates

The structure refinement of synthetic hafnon gives space group I41/amd with a 6.5725(7), c 5.9632(4) A, Z = 4, D 6.97 g/cm3. Combination of hafnon, zircon and thorite structure refinements gives O-positions and bond lengths for actinide orthosilicates as well as the possible extent of solid solution...
