DESCRIPTION
The literature review on alternative materials for the manufacture of membranes intended for oxygen separation had as its main objective the improvement of the thermo-mechanical behavior, with a focus on solving the problems related to metal-ceramic junctions. The analysis shows that dual phase membranes exhibit greater resistance to chemical expansion phenomena in comparison with LSCF and BSCF single phase membranes. This results in a more linear thermal expansion with temperature and a lower thermal expansion coefficient, making dual phase composites particularly suitable for metal-ceramic junctions. It is clear from the literature that the focus of research should be on improving stability, both thermo-mechanical and chemical, under operating conditions in order to bring membrane technology closer to real-world applications.
 
APPLICATIONS
The literature review on alternative materials for preparing membranes for oxygen separation can be applied in research aimed at exploiting industrial thermal waste for the energy-efficient production of oxygen in industrial processes.
