Refractory product having high zirconia content |
| abstract |
The present invention relates to a molten cast refractory comprising the following constitution, which is represented by a weight percentage based on an oxide and wherein the total sum of the oxides is equal to 100% ZrO 2 + Hf 2 O: balance up to 100% 4.5% <SiO 2 <6.0% Al 2 O 3 < 0.80% 0.3% < B 2 O 3 < 1.0% Ta 2 O 5 + Nb 2 O 5 ≪ 0.15% Na 2 O + K 2 O < 0.1% K 2 O < 0.04% CaO + SrO + MgO + ZnO + BaO < 0.4% P 2 O 6 < 0.05% Fe 2 O 3 + TiO 2 ≪ 0.55% Optionally, Y 2 O 3 other oxides species (Y 2 O 3 <0.3% ) containing <1.5%, (Provided that the weight ratio of non-Al 2 O 3 / B 2 O 3 expressed as "A / B" is between 0.5 and 2.0 and the invention can be used in a glass melting furnace) |
