Simulation of corrosion of a refractory material by Al2O3-CaO liquid oxides

Jacques Poirier is Professor at Polytech Orleans

Activities :

  • The corrosion of refractory materials by gases, metals and liquid oxides at high temperature :
    • The identification of the chemical reactions, modelling of the thermochemical mechanisms
    • Transport of the liquid phases in the capillary network and impregnation modelling
    • Relation between thermochemical and thermomechanical damage.
  • Evolution of mineral phases and glasses at high temperature
    • Microstructural observations
    • Thermodynamic interpretation and kinetic modelling
  • Development of better-adapted materials for specific applications

Experimental facilities :

  • Optical microscopy, scanning electron microscopy, X-ray analysis, poresizer measurement, laser granulometry, specific area measurement….
  • Heating up to 1700C, simulation of thermal shocks and corrosion equipments
