Nucleation of solid solutions crystallizing from aqueous solutions.
The study of nucleation and growth mechanisms of salts from aqueous solutions, as a function of supersaturation, is described using both macroscopic and microscopic experiments. In situ observations in a fluid cell in an atomic force microscope (AFM) reveal phenomena not accounted for in standard crystal-growth theories, specifically on the role of the crystal structure of the substrate in cont...
متن کاملSolid aqueous solutions
In most treatments of aqueous "solutions" it is taken for granted that water is present in the liquid state and in excess, with the concentrations of solutes limited by their saturation solubilities. Hence, the thermodynamic reference states are defined as the infinitely dilute solution, a solution of unit molality, etc. In recent years supersaturated aqueous solutions have been receiving incre...
متن کاملThe kinetics of nucleation of solid solutions from aqueous solutions: A new model for calculating non-equilibrium distribution coefficients
The nucleation kinetics of binary solid solutions, with general formula BxC1-xA, crystallising from aqueous solution can be described using a generalised expression for the nucleation rate: the function, J(x), in which supersaturation, interfacial free energy and other parameters of the classical nucleation rate equation are considered as functions of the solid composition. As an example, we st...
متن کاملMolecular-scale formation of carbonate solid solutions from multicomponent aqueous solutions and other related phenomena
This work deals with the growth behaviour of calcite surfaces in contact with multicomponent carbonate aqueous solutions containing divalent cations (Ba, Sr, Mn, Cd or Mg). The result of solid surface-aqueous solution interactions is the formation of solid solutions, with calcite as one of the end-members. In situ Atomic Force Microscopy and other surface techniques have revealed a wide variety...
متن کاملHomogeneous nucleation temperatures in aqueous mixed salt solutions.
This is the first report on the measurement of homogeneous nucleation temperature, TH, in the presence of aqueous mixed salt systems of varying compositions and ionic strengths. The TH,m (TH value in aqueous mixed salt system) data for these systems have been analyzed in terms of a simple empirical equation. The TH,m values in simple aqueous mixed salts like NaCl-KCl can be approximated by line...
