SOLID SOLUTIONS - A HUME-ROTHERY CONDITION IN THE CONTEXT OF THE SET-THEORETIC NOTION OF BINARY RELATION

Michal Michalak, Grzegorz Bytomski

Abstract

In this paper, the authors discussed one of the Hume-Rothery conditions for occurring substitutional solid solutions in the context of binary relations. The analyzed condition says that substitutional solid solutions may form if the ionic radius of the solute and solvent ions differ by no more than 15%. Because the problem concerns a mathematical connection between two objects, the authors suggested describing this problem using the set-theoretic notion of binary relation. In this context, the possibility of forming solid solutions is reduced to meeting a mathematical condition accompanying the introduced binary relation. From a mathematical point of view, it seems to be natural to check whether the introduced relation can be treated as an equivalence relation. The authors presented a proof that such a relation is not an equivalence relation as it does not meet all the necessary conditions (reflexive, symmetric and transitive) for an equivalence relation. There is presented the main consequence of this result пїЅ nonexistence of equivalence classes that in terms of the described problem represent disjoint sets containing ions that form solid solutions.
