THE THERMODYNAMICS OF GROSSLY NON-STOICHIOMETRIC OXIDES AND OF IONIC LIQUIDS (SUCH AS UO-2) OF NUCLEAR IMPORTANCE AS UNDERSTOOD BY MEANS OF SPACING STATISTICS (INVITED PAPER).
The general theory of spacing statistics consists of assigning to each particle of an ensemble in a volume V an interaction envelope (or spacing) and a well defined energy level (spacing level). The theory is based on an expansion of the total interaction energy of the ensemble in terms of the set of one particle energies for a set of lattices occupying the same volume V. This theory has been applied: a) to interacting point defects and clusters, in grossly non-stoichiometric oxides; b) to liquids, and, in particular, ionic liquids and UO-2. For defects, the high temperature, monophasic thermodynamic functions are described; in particular, the size defect or cluster aggregations can be evaluated from the slopes of the chemical potential curves. For liquids, good results are obtained: 1) for their critical parameters, 2) for the critical (non-classical) exponents.
