Ionic solid solution

An analysis of a large amount of experimental data by Davies and Navrotsky has also shown that the enthalpy of mixing of ionic solid solutions correlates with the volume mismatch [39], The volume mismatch was in the simplest case assumed to... 

Ionic Solid Solutions in Contact with Aqueous Solutions... 

An ionic solid solution, on the other hand, is of variable composition. Its chemical formula can not be written in simple integer ratio numbers. A theoretical example is that of two compounds AX and BX which form a solid solution of the general formula ... 

In most cases the study of equilibria between solid solutions and aqueous solutions containing their ions is extremely difficult, since solid state diffusion is virtually absent at ordinary temperatures. Most ionic solid solutions can be made homogeneous only at temperatures above 500°C, where solid state diffusion is relatively fast. 

Substitutional Disorder In Regular Solid Solutions. Most simple ionic solutions in which substitution occurs in one sublattice only are not ideal, but regular 2, J3) Most complex ionic solid solutions in which substitution occurs in more than one sublattice are not only regular in the sense of Hildebrand s definition (15) but also exhibit substitutional disorder. The Equations describing the activities of the components as a function of the composition of their solid solutions are rather complex ( 7, V7, 1 ), and these can be evaluated best for each individual case. Both type II and type III distributions can result from these conditions.

In this chapter, we will examine two cases where that modeling enables us to correetly represent the behavior of the poly-constituent solid phase. We will look, in turn, at the study of ionic solid solutions and the fixation of water molecules in the lattices of salts.
