Fused zirconia refractory materials having high-temperature resistance and corrosion resistance which includes 1 - 30 wt% of calcia and 0.05 - 2 wt% of yttria or rare earth minerals including yttria as a stabilizer of zirconia, which are produced by the process comprising adding and mixing calcia and yttria or rare earth minerals including yttria to zirconia materials as a stabilizer, fusing the mixed materials in an electric arc furnace, cooling slowly the fused materials to obtain an ingot, crushing the ingot to particles and oxidizing and annealing the particles. |
