Amorphous state

{
  "id": "MLC-T-CHM-000506",
  "term": "Amorphous state",
  "field": "Chemistry",
  "definition": "A solid state of matter characterized by a disordered arrangement of molecules, lacking the long-range periodic order found in crystalline solids. In polymers, this state is defined by the random entanglement of polymer chains. Materials in this state exhibit a glass transition temperature rather than a sharp melting point.",
