Abstract
Abstract A metal composition usable as a brazing material for bonding a metal to a non-oxide ceramic. The brazing material contains, at least, one or more metals selected from a first group of transition metals consisting of Pt, Pd, Rh, Ir, Ru and Os, and one or more metals selected from a second group of transition metals consisting of Cr, Mn, Fe, Co, Ni and Cu. The material may further contain one or more elements selected from a third group of elements consisting of B, C, Si and P.
