Peritectoid reaction

{
  "id": "MLC-T-CHM-008658",
  "term": "Peritectoid reaction",
  "field": "Chemistry",
  "definition": "An invariant reaction in a phase diagram where two solid phases react isothermally to form a new, different solid phase upon cooling. This reaction occurs at a specific temperature and composition, where three solid phases coexist in equilibrium. It is analogous to a peritectic reaction but involves only solid phases.",
