      abstract     = {The structural integrity of the sealing material is
                      critical for the reliability of solid oxide
                      fuel/electrolysis stacks. The current work concentrates on
                      microstructural and mechanical aspects of a sealant material
                      for this application. In particular, the crystallization
                      behavior as a determining factor for the sealants’
                      mechanical behavior is investigated via high-temperature XRD
                      for 24 h. Furthermore, regarding mechanical properties,
                      three- and four-point bending tests are carried out on
                      sealant bars and head-to-head joined specimens at room- and
                      high-temperatures, yielding in particular relevant fracture
                      stress data. In addition, the elastic modulus is measured by
                      the impulse excitation test from RT to 900 ºC. Tests are
                      done for both as-sintered (as-joined) and annealed samples.
                      The main crystallization appears to happen during the
                      initial joining time. The sealant shows a relatively stable
                      flexural strength in terms of temperature dependency as well
                      as effects of the aging process. In fact, the joined
                      specimens reveal a more than $50\%$ lower flexural strength
                      than glass bars at all temperatures. A complementary finite
                      element simulation indicates the presence of a
                      non-negligible thermal residual stress in joined specimens.},
