Urania-lanthana compositions were studied by x-ray diffraction, chemical analysis, and polished-section techniques to determine cubic fluorite solubility, lattice parameter values, stoichiometry, and microstructure. An appreciable variation in fluorite lattice parameter with composition existed for vacuum, hydrogen, and oxidizing heat treatments. The volatility behavior of urania-lanthana solid solutions was investigated by heating for extended time intervals in an oxidizing atmosphere.
