Title: Shape Effect in Layering of Solid Solutions in Small Volume: Bismuth–Antimony Alloy

Abstract

The regularities of the effect of the shape of interphase boundaries in small volume systems on the separation of solutions with an upper critical solution temperature (UCST) are described by the example of Bi–Sb alloy particles with a core–shell configuration. The change in the shape of interphase boundaries is simulated in general by introducing a parameter corresponding to the degree of deviation of the shape of the boundaries from the spherical one. An analysis of the extrema of the Gibbs function revealed regularities in the effect of the shape of the core and shell phases on phase equilibria, the thermodynamic stability of heterogeneous states, and the phase separation diagram. The deviation of the shape of the interphase boundaries from the spherical shape changes the UCST and the mutual solubility of the components. The deformation of the shell of a core–shell particle increases the thermodynamic stability of the heterogeneous state, which contributes to the separation of the solution. The deformation of the core lowers the thermodynamic stability of the heterogeneous state and expands the range of metastable states.
