  • Molecular alloys and restoring thermal energy by phase change
    Patent number: 6136217
    Abstract: Compositions made up of one or more molecular alloys which are suitable for storing or restorng thermal energy at a temperature level T and over a time interval .delta. matching those required for a pareicular applicaion as a phase-change material, said alloys belonging to a phase diagram having a transition region wih a temperaure range which includes the required temperatre and has a near-horizontal geometric locus (EGC). Said compositions are useful as a phase-change materials, particularly in the agrifoodstuffs and paramedical industries.
    Type: Grant
    Filed: March 2, 1999
    Date of Patent: October 24, 2000
    Assignee: Centre National de la Recherche Scientifique
    Inventors: Yvette Haget, Denise Mondieig, Miguel-Angel Cuevas-Diarte
  • Molecular alloys for storing and restoring thermal energy by phase change
    Patent number: 5997762
    Abstract: Compositions made up of one or more molecular alloys which are suitable for storing or restoring thermal energy at a temperature level T and over a time interval .delta. matching those required for a particular application as a phase-change material, said alloys belonging to a phase diagram having a transition region within a temperature range which includes the required temperature and has a near-horizontal geometric locus (EGC). Said compositions are useful as a phase-change materials, particularly in the agrifoodstuffs and paramedical industries.
