Improved thermal shock resistant refractories from plasma-dissociated zircon

  • R. C. Garvie


Dissociated zircon (DZ), produced in a plasma furnace recombined and sintered to about 92% of the theoretical density in the range 1300 to 1500° C The work-of-fracture of DZ increased from 20J m−2 to 73 J m−2 with additions of 10 wt% monoclinic zirconia particles which had a mean diameter of about 13μm. Thermal shock data showed that crack propagation in DZ/ZrO2 composites was stable.
