The inventive sintered product is produced from an initial feedstock having a zirconium content ranging from 75 to 99% and the following average chemical weight composition, in percentage by weight, based on oxides: 60 %=ZrO 2 +HfO 2 =75%, 27%=SiO 2 =34%, 0.2=TiO2=1.5 %, 0.3<Y 2 O3=3.5 %, other oxides:=1%, to give a total of 100%. Said product can be used for glassworks. |
