WebThe term phase refers to any compositionally and physically distinctive substance. Phases may be solids, liquids or gases. Phase equilibria involve chemical reactions when one or more phases react to form different phases. Minerals and mineral assemblages may be at stable, metastable, and unstable equilibrium. WebA peritectic reaction is a reaction where a solid phase and liquid phase will together form a second solid phase at a particular temperature and composition - e.g. Liquid + alpha --> beta These reactions are rather sluggish as the product phase will form at the boundary between the two reacting phases thus

WebApr 12, 2024 · These three phases can coexist at equilibrium at \(0\units{\(\degC\)}\). A phase transition like this, in which a solid compound changes into a liquid and a different solid, is called incongruent or peritectic melting, and the point on the phase diagram at this temperature at the composition of the liquid is a peritectic point.
