High Performance Ceramics

Which type of material is suitable as immobilization barrier for waste respectively as cladding for fuel elements?
Following indispensable requirements have to be fulfilled:

  • high corrosion resistance in acidic, neutral and basic environment
  • high temperature stability at variable atmospheres
  • high thermal conductivity and shock resistance
  • diamond-like hardness
  • radiation resistance
  • gas tightness (no open pores)
  • high mechanical, especially compression strength
