A refractory article having a support structure including a first plurality of posts coupled by a first member; and a second plurality of posts substantially parallel with the first plurality of posts, the second plurality of posts coupled by a second member, wherein the support structure has a height, H, and wherein the first and second members are positioned between 0.3H and 0.7H. In another aspect, the support structure has a height to width ratio of at least 1.5, a stiffness factor of no greater than 100 mm, and a solid to open volume ratio of no greater than 5%. In another aspect, the support structure has a weight of no greater than 1200 kg, a stiffness factor of no greater than 100 mm, and a solid to open volume ratio of no greater than 5%.

Refractory article

A refractory article including a body having central opening extending through at least a portion of the body, the central opening having a receiving surface having a convex curvature. In an embodiment, the body can include a coupling protrusion extending from a portion of an upper surface of the body and a coupling depression on a portion of a bottom surface of the body.

A refractory article can include a socket including a cavity that is configured to receive a post, a particulate material, and a binder. The binder is configured to bond the post to the socket. The refractory article can include a sleeve coupled to the socket and configured to bond the post to the socket. In an embodiment, the sleeve can bond to the binder. In another embodiment, a collar can be placed between the sleeve and the binder. The collar can be configured to bond the post to the socket. A method of forming a refractory article can include disposing a particulate material within a cavity of a socket and placing a binder material overlying the particulate material.
