An article used for thermal protection includes a base structure having at least one surface. The base structure is made of a ceramic oxide material. A silicide coating is formed on the at least one surface of the base structure. The coating comprises a refractory metal and silicon, which together form a silicide. The coating is at least partially diffused into the base structure at the at least one surface.

1. A method of forming a coated thermal insulation article, comprising the steps of:forming a base structure from a ceramic oxide material; forming a silicide slurry from a flux agent, a liquid carrier constituent and a powdered constituent which contains silicon and a refractory metal; applying the slurry in a predetermined coating weight to a surface of the base structure; and heating the coated base structure in an oxidizing environment for a time and temperature sufficient to form a solid, substantially 100% silicide coating which is fused to the base structure.
