The new developed Keramex-mixture offers the following advantages compared to other refractory materials:
  • Longer service life due to higher oxidation resistance
  • Low porosity due to very small and partially closed pores
  • Well suited for use under heavy load due to a higher modulus of rupture
  • Higher quality due to flatness of setting throughout the service life
