Web6: Phase transition of pure compound, one component, two phases, solid → solid 7: Eutectic, two components, three phases, L solid → solid + solid The last example (7) is really hard to observe in the phase diagram, but really is there. It is however not a necessity since it also can be described by a peritectic reaction at this place as well. WebPeritectic point – The point on a phase diagram where a reaction takes place between a previously precipitated phase and the liquid to produce a new solid phase. When this point is reached, the temperature must remain constant until the reaction has run to completion. Read More: Can a Mexican live in Spain? What is the peritectic temperature?
