Abstract: A refractory object can include at least approximately 10 wt % Al2O3 and at least approximately 1 wt % SiO2. In an embodiment, the refractory object can include an additive. In a particular embodiment, the additive can include TiO2, Y2O3, SrO, BaO, CaO, Ta2O5, Fe2O3, ZnO, or MgO. The refractory object can include at least approximately 3 wt % of the additive. In an additional embodiment, the refractory object can include no greater than approximately 8 wt % of the additive. In a further embodiment, the creep rate of the refractory object can be at least approximately 1×10−6 h−1. In another embodiment, the creep rate of the refractory object can be no greater than approximately 5×10−5 h−1. In an illustrative embodiment, the refractory object can include a glass overflow trough or a forming block.

Abstract: A zircon body for use in glass manufacturing is provided containing zircon grains and an intergranular phase present between the zircon grains. The intergranular phase may contain silicon oxide. The body may be exposed to a halide to at least partially remove at least a majority of the silicon oxide contained in the intergranular phase from the outer portion or to at least partially remove the intergranular phase along an outer portion of the component.

Abstract: A component includes a body including zircon (ZrSiO4) grains, the body having a free silica intergranular phase present between the zircon grains and distributed substantially uniformly through the body. The body comprises a content of free silica not greater than about 2 wt. % for the total weight of the body.
