Mixed ionic-electronic conducting(MIEC) dense ceramic membrane shave attracts considerable attraction because of their application in oxygen separation, catalytic membrane reaction and oxyfuel combustion processes. Reactive air brazing (RAB) is the mostly used technique for joining high-temperature structural ceramic components. But two disadvantages of the RAB joints must be come into notice .One is the high porosity which can lessen gas tightness and the other is the brittle reaction layer which can decease the strength of the joint . In this study, the brazing processes were developed in air, high-purity argon with different Ag-Cu braze alloys respectively. The results show that, with the high-purity argon as the protective atmosphere during the brazing process, the porosity was reduced and the desired brittle reaction layer was obtained. The interfacial reaction layer thickness of Ag based brazes/BaCo0.7Fe0.2Nb0.1O3-δ(BCFNO) as a function of Cu content at three conditions was also studied.
