摘要
The invention relates to a sintered product made from a starting charge containing 5 to 50% zircon and having the following chemical composition, in percentages by weight on the basis of the oxides and for a total of more than 100%: silica and zirconia, the concentration of zirconia (ZrO2) being equal to at least 64%; at least 0.2% of a dopant selected from among V2O5, Nb2O5, Ta2O5 and mixtures thereof; optionally a stabiliser selected from among Y2O3, MgO, CaO, CeO2 and mixtures thereof, at a concentration less than or equal to 6%; and "other oxides" at a concentration less than or equal to 6.7%.
