Abstract: In this thesis, different glass-based sealants were developed for joining oxygen transport membranes (OTM) to obtain matching the coefficient of thermal expansion (CTE) with membrane and support metals. The crystallization behavior of the BaO–CaO–SiO2–B2O3 system glass (H)and BaO–SrO–SiO2–B2O3 system glasses (BS) will be discussed. In addition, the glass-forming stability of glass matrices, filler type and amount effect on CTE, chemical compatibility, mechanical strength, shrinking behavior, viscous flow property, joining behavior, thermal cyclingand long-term thermal stability were analyzed for various glass-based sealants. The feasibility of the fast joining process was also investigated to economize the energy costs of the heating process. SrTi0.75Fe0.25O3-δ (STF25) was used as an OTM, and the sealing partners were ferritic steelAluchrom, pre-oxidized Aluchrom and Crofer22APU.
