Refractory object

A refractory object can include Al2O3 at a content in a range of approximately 10 wt% Al2O3 to approximately 94 wt% Al2O3; SiO2 at a content of at least approximately 1.1 wt% SiO2; an additive at a content of at least 0.2 wt% additive. The additive can include TiO2, Y2O3, CaO, MgO, or any combination thereof. The creep rate of the refractory object can be no greater than approximately 1 x 10-4 h-1.
