Joining of Ion Transport Membranes Using a Novel Transient Liquid Phase Process
A novel transient liquid phase (TLP), or partially transient liquid phase (PTLP) ceramic-ceramic joining process has been developed that leaves behind no interfacial phase, enabling the fabrication of complex systems of components. The process can be used to join and manifold components and reduce the sintering temperatures of ion transport membranes. This process has been tested in the joining of high temperature perovskite ion transport membranes. Utilizing metal oxides mixed at low melting point compositions of their respective systems, then combined with a more refractory compound, the process has resulted in a strong joint with low porosity that is hermetic to helium.
