Vantendeloo: Philosophical Magazine B 1991, vol. If we look at the net ionic equation for this reaction it shows that the driving force for the reaction is the production of water: H+(aq) + OH-(aq) H2O (l) When you react the acid and base, this process is called neutralization. Mills: Metallurgical and Materials Transactions A 2018, vol. Example: HCl (aq) + NaOH (aq) NaCl (aq) + H2O (l) NaCl is the salt is this reaction and you already know water.

To predict the product of a precipitation reaction, all species initially present in the solutions are identified, as are any combinations likely to produce an insoluble salt. Lacaze: Materials characterization 2010, vol. In a precipitation reaction, a subclass of exchange reactions, an insoluble material (a precipitate) forms when two electrolyte solutions are mixed.

Following this, we investigate two symmetry-breaking transitions (cubic to tetragonal) and (hexagonal to orthorhombic), that lead to the formation of multi-variant clusters where we study the organization of the precipitates as a function of the elastic properties of the precipitate and the matrix.Ī. The first is the classical two-phase precipitate reaction that leads to the formation of core–shell microstructures, where we clarify the influence of elasticity on the formation of such clusters. Using this technique, we investigate the precipitate organization for three solid-state reactions. Here, we utilize the phase-field framework to minimize the sum of the elastic and the interfacial energies for a given volume of the precipitates using an extension of the volume-preserved Allen–Cahn algorithm (Garcke et al. In this paper, we formulate a phase-field model for the computation of equilibrium configurations of multiple phases that arise out of a solid-state precipitate reaction, in the presence of coherency stresses. ![]()
