Abstract
A method for joining, assembling, at least two parts made of silicon carbide-based materials by non-reactive brazing is provided. According to the method, the parts are contacted with a non-reactive brazing composition, the assembly formed by the parts and the brazing composition is heated to a brazing temperature sufficient to melt the brazing composition totally or at least partly, and the parts and the brazing composition are cooled so that, after solidification of the brazing composition, a moderately refractory joint is formed; wherein the non-reactive brazing composition is a binary alloy consisting in atomic percentages, of 60% to 66% silicon and 34 to 40% nickel. A brazing composition as defined above is also provided. A paste, suspension of braze alloy comprising a powder of the brazing composition and an organic binder is provided. In addition, a joint and assembly obtained with the foregoing method is provided.
