A refractory article includes a body including a ceramic having an aluminosilicate present in an amount of at least 70 wt % and not greater than 99 wt % for a total weight of the body, and the body further includes a dopant including a Mg-containing oxide compound and a Fe-containing oxide compound, and the dopant is present in an amount within a range including at least 1 wt % and not greater than 12 wt %.

Refractory article and method of making

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 AlOcontaining 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 SiOcomponent for a total weight of the zircon body.

Sintered zircon material for forming block

A component includes a body including zircon (ZrSiO) 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.
