Abstract
This invention provides a shaped ceramic composite article comprising ceramic oxide fiber(s), a first coating comprising a carbonaceous matrix which includes boron nitride particles in contact therewith, and a second coating comprising silicon carbide. The inventive composite article is useful in applications requiring good heat resistance and mechanical properties, such as gas fired radiant burner tubes, gas burner nozzle liners, heat exchangers, thermowells, core busters or flame dispersers, and other gas fired furnace components.
