METHOD FOR ASSEMBLING NON-REACTIVE REFRACTORY BRAZING PIECES OF SIC MATERIALS, BRAZING COMPOSITION, AND REFRACTORY SEAL AND ASSEMBLY OBTAINED THEREBY

摘要

A method of assembling at least two pieces of silicon carbide materials by nonreactive refractory brazing, wherein these parts are brought into contact with a non-reactive brazing composition and the assembly formed by the parts and the solder composition at a soldering temperature sufficient to melt the solder composition to form a refractory seal, wherein the non-reactive solder composition is comprised, in atomic percentages, of 40 to 97% silicon and 60 to 3% of another element selected from chromium, rhenium, titanium, vanadium, ruthenium, iridium, rhodium, palladium, cobalt, platinum, cerium and zirconium and in which, previously at brazing, an addition of SiC reinforcement and / or C.Braiding composition, composition for refractory brazing is carried out. Refractory joint and assembly obtained by the process.
