Abstract
A refractory object may include a zircon body that may include at least about 0.1 wt. % and not greater than about 5.5 wt. % of an Al2O3 containing component for a total weight of the zircon body. The zircon body may further include at least about 25 wt. % and not greater than about 35 wt. % of a SiO2 component for a total weight of the zircon body.
Claims14
A refractory object comprising:
- a zircon body, wherein the zircon body comprises:
- at least 25 wt. % and not greater than 35 wt. % of SiO2 component for a total weight of the zircon body;
- a Al2O3 component not greater than 4.5 wt. % for a total weight of the zircon body;
- and
- Yb2O3 at a content of at least 0.1 wt % for a total weight of the zircon body.
