Refractory ceramic composites with methods of making

Composites en céramique réfractaire avec procédés de fabrication

Feuerfeste Keramikverbundstoffe mit Herstellungsverfahren

Abstract

A refractory ceramic composite having a fibrous ceramic core (12) and a solid ceramic coating (14) is provided. An intermediate for making refractory composite ceramics is also provided. The intermediate includes a reaction product of a refractory metal and a carbon based felt, wherein a quantity of the refractory metal present is stoichiometrically non-equivalent to a quantity of carbon present during the formation of the reaction product so that the reaction product comprises a ceramic based felt having free, unreacted refractory metal thereon.
