SOLVOLYTIC DISPROPORTIONATION OF NONSTOICHIOMETRIC OXIDES OF PRASEODYMIUM AND TERBIUM
Partly presented in the Third Rare Earth Research Conference, 1963.
The solvolytic disproportionation of non-stoichiometric PrOx and TbOx in acid solutions to produce higher oxides has been investigated. Some new non-stoichiometric phases have been reported. A number of interesting features of the non-stoichiometric rare earth oxides have been discussed and the need for a satisfactory structural model has been pointed out.
