A refractory article includes a body having a first portion defining at least a portion of a first exterior surface of the body, the first portion including a carbide, and further including a second portion defining at least a portion of a second exterior surface of the body opposite the first exterior surface, the second portion including an oxide, and a thermal conductivity difference (&#x394;TC) of at least 10 W/mK between the first exterior surface and the second exterior surface, and an average Shell Temperature of not greater than 400&#xb0; C.

Refractory articles and methods for forming same

A refractory article can include a body including a content of alumina of at least 60 wt %, a content of silica of not greater than 20 wt %, a content of zirconia of not greater than 20 wt % for a total weight of the body. In a particular embodiment, the body includes a third phase including composite grains including mullite and zirconia. The third phase including the composite grains can be present within a range including at least 1 wt % and not greater than 35 wt % for a total weight of the body.
