The present invention seeks to provide a product with improved creep strength that can be used in a glass furnace. The present invention provides a sintered product made from a starting mixture containing 75% to 99% zircon and having the following mass average chemical composition such that the total is 100% by weight percent of the oxide base: . The present invention also provides for the use of refractory products in a glass furnace. 60% ≦ ZrO 2 + HfO 2 ≦ 75%, 27% ≦ SiO 2 ≦ 34%, 0.2% ≦ TiO 2 ≦ 1.5%, 0.3% ≦ Y 2 O 3 ≦ 3.5%, Other oxides ≦ 1%. |
