Abstract:
The present invention relates to a sintered product elaborated from a starting charge containing 75-99% of zircon, in mass percentage based on the oxides and having the following average weight chemical composition, in mass percentages based on the oxides 60%≦ZrO2≦72.8%, 27%≦SiO2≦36%, 0.1%≦B2O3+GeO2+P2O5+Sb2O3+Nb2O5+Ta2O5+V2O5, 0.1%≦ZnO+PbO+CdO, B2O3+GeO2+P2O5+Sb2O3+Nb2O5+Ta2O5+V2O5+ZnO+PbO+CdO≦5%, 0%≦Al2O3+TiO2+MgO+Fe2O3+NiO+MnO2+CoO+CuO≦5%, other oxides: ≦1.5%, for a total of 100%. Notably used in a glass furnace.
