Solvolytic disproportionation of non-stoichiometric
Oxides of praseodymium
Abstract
The solvolytic disproportionation of non-stoichiometric PrOx 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.
