Abstract
Dense monolithic SiC or SiC ceramic composites are strongly bonded using brazing compositions which, in their preferred composition, include a braze alloy consisting essentially of less than 50 weight percent silicon and at least two metals from the group of Fe, Cr, Co and V and produce a joint suitable for use in a high neutron flux environment. Brazing is carried out at a temperature of about 1200.degree. to 1500.degree. C. in an inert atmosphere and is complete in about 15 minutes. Broadly, a genus of brazing compounds are disclosed which include between about 10 and about 45 weight percent silicon and at least two elements selected from the following group: Li, Be, B, Na, Mg, P, Sc, Ti, V, Cr, Mn, Fe, Co, Zn, Ga, Ge, As, Rb, Y, Sb, Te, Cs, Pr, Nd, Ta, W and Tl.
