Glatt Powder Synthesis in the joint project “SaMBa”
Adaptation of particle morphology to optimize BSCF for use in oxygen membranes
Novel manufacturing process for highly permeable oxygen membranes and development of an innovative membrane connection plate for oxygen generators
The “SaMBa” project was based on the use of the new material BSCF (Ba0,5Sr0,5Co0,8Fe0,2O3-x), which was to be optimized for O2 separation by adapting the particle morphology to subsequent processing into membrane components. The goal was to minimize the grain size to produce the thinnest possible membrane after sintering as thinner membranes increase O2 permeability. In addition, it was to be investigated how BSCF waste – such as processing residues – can be recycled through treatment processes. The operating behavior of the entire system equipped with O2 membranes was recorded experimentally and simulated in parallel by FEM.
The aim was to determine suitable operating conditions for the permanent, efficient and safe operation of O2 membrane systems and also to identify suitable peripheral components for a connection plate suitable for series production, on the basis of which larger membrane systems can be designed.
As part of the “SaMBa” project, Glatt used Powder Synthesis to produce the raw material powders in the appropriate particle size and phase composition for use in further process steps. In comprehensive synthesis tests, the specific influences of the process parameters on particle formation were investigated. It was shown that both the frequency and the spray pressure influence the particle properties with regard to particle size, particle size distribution and yield. With regard to the chemical conversion of the mixed oxides, it was found that this can be directly influenced by the process temperature as well as the pulse amplitude and its combination with the frequency.

“SaMBa” research project: Novel manufacturing process for highly permeable oxygen membranes and development of an innovative membrane connection plate for oxygen generators
“Mixed ionic electronic conductor” (MIEC) membranes are specialized inphase materials which exhibit significant electron and ionic conductivity. Therefore, neutral molecules can be transported through a solid membrane and thus separated from other components. One such material is BSCF (barium-strontium-cobalt-iron oxide), which enables efficient oxygen exchange. The production of BSCF by Glatt Powder Synthesis and the efficiency of the produced membranes was the focus of this research.
