Abstract
A refractory braze composition and process for assembling alumina-containing parts to another alumina-based material, metal or a metal alloy by reactive or non-reactive refractory brazing using a braze composition provide assemblies entirely of alumina or containing alumina and a metal or metal alloy. The braze composition is non-reactive with alumina or a reactive composition, whose reactivity with alumina is controlled, and it is formed of aluminium, of titanium, and of a matrix made up either of palladium, or of nickel, or of a nickel and palladium alloy.
