abstract = {Advanced design concepts for the application of oxygen
transport ceramic membranes are based on thin layers
supported by porous substrates. One suitable support
material in this respect is porous MgO. However, a careful
consideration of the mechanical stability is required to
warrant long term performance and reliability under
application relevant thermo-mechanical loads. The current
work summarizes the effect of the sintering conditions on
porosity and mechanical properties and gives elastic modulus
and fracture stress as a function of temperature. An
enhancement of the strength by the addition of boehmite to
MgO was tested. Elastic moduli are determined and compared
as obtained by indentation and bending tests. With respect
to fracture, specimens in planar geometry are investigated
using ring-on-ring bending tests; tubes are tested using an
O-ring set-up. Fracture stresses are statistically analyzed.
The obtained mechanical parameters are compared to that of
other potential porous substrate materials.},
