PURPOSE:To obtain a zirconia refractory having improved fire-resistance, corrosion resistance and spalling resistance by laminating and integrating a partially or completely stabilized ZrO2 composition containing Y2O3 and a partially or completely stabilized ZrO2 composition containing CaO and sintering the laminated product. CONSTITUTION:A partially or completely stabilized ZrO2 composition containing 4-10mol% of Y2O3 and a partially or completely stabilized ZrO2 composition containing 5-15mol% of CaO are filled in a mold to form prescribed shape and thickness, compression-molded to integrate both compositions and sintered at >=1500 deg.C to obtain the objective refractory. |
