Abstract : The patent concerns a heat-resistant salt-free ceramic material especially suitable for use as a tooling mandrel for assemblies to be welded or brazed where the temperature of the entire mandrel is not raised above approximately 600F., and where the temperature adjacent to the mandrel is highly localized and of short duration. The invention material is thus especially suitable for electron beam welding, percussive arc welding, and induction brazing where heating is confined to a small portion of the article to be brazed. The material readily disintegrates or slakes when impinged with jets of hot water following the welding or brazing operation.
