The invention provides a novel fused cast refractory article with a high zirconium dioxide content, having improved electrical resistivity. The specified refractory article contains, in wt.%, Relative to oxides, and the total amount is more than 98.5%: ZrO + HfO> 85; SiO1-10; AlO0.1-2.4; VO <1.5, and an additive selected from the group formed by VO, CrO, NbO, MoO, TaO, WO and their mixtures, and the weighed amounts are such that 0.2% ≤8.84CrO + 1.66NbO + 6.14MoO + TaO + 3.81WO. |
