Abstract:
The invention provides a novel fused and cast refractory product with a high zirconia content having improved electrical resistivity. Said refractory product comprises, as a percentage by weight relative to the oxides and for a total of more than 98.5%: ZrO2+Hf2O: >85% SiO2: 1% to 12% Al2O3: 0.1% to 2.4%, with Al2O3/SiO2
