Abstract:
A refractory object can include at least approximately 10 wt% A12O3 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 x 10-6 h-1. In another embodiment, the creep rate of the refractory object can be no greater than approximately 5 x 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 tin oxide-based electrode formed from a composition including a majority component comprising tin-oxide (SnO2), and additives comprising CuO, ZnO, and a resistivity modifying species. The total amount of CuO and ZnO is not greater than about 0.3 wt%, and the ZnO is present in an amount within a range between about 0.1 wt% and about 0.19 wt%.
