Abstract
Process for the moderately refractory assembly of at least two articles made of silicon carbide-based materials by non-reactive brazing in an oxidizing atmosphere, in which the articles are placed in contact with a non-reactive brazing composition and the assembly formed by the articles and the brazing composition is heated in an oxidizing atmosphere at a brazing temperature sufficient to melt the brazing composition so as to form a moderately refractory joint, wherein the non-reactive brazing composition is a composition A composed of silica (SiO2), alumina (Al2O3) and calcium oxide (CaO), or alternatively a composition B composed of alumina (Al2O3), calcium oxide (Cao) and magnesium oxide (MgO).Brazing suspension, paste comprising a powder of said brazing composition and an organic binder.Refractory joint and assembly.
