New article about perovskite-like material by spray pyrolysis method for oxygen separating membranes application

2018 / 07 / 12

In the magazine Ceramic Materials (Vol: 70, Issue: 1, 2018) there was published the article entitled: Synthesis of Ba0.5Sr0.5Co0.8Fe0.2O3-δ perovskite-like material by spray pyrolysis method for oxygen separating membranes application, co-authored by Magadalena Gromada (PhD), researcher from IEn's CEREL (Boguchwała). The publication presents results of 2017 statutory work no.OC/01/STAT/17.

The Ba0.5Sr0.5Co0.8Fe0.2O3-δ (BSCF) mixed oxide with perovskite-like structure was synthesised by a spray pyrolysis method. The calcination temperature required to obtain a single phase material was determined by DTA/DTG analysis. Physical and chemical properties of the obtained powder (morphology, texture, phase composition and particle size distribution) were determined. The BSCF powder was granulated in order to improve its compactibility. The green compacts of BSCF material were moulded by combined uniaxial and isostatic pressing. An optimal curve which ensure high density of obtained sinters has been elaborated. The key parameters that determine the suitability of the BSCF material for the oxygen separating membranes forming i.e.: apparent density, open porosity, water absorbability and surface microstructure were determined. The obtained outcomes confirm that the BSCF perovskite powder prepared by the spray pyrolysis method possesses the appropriate properties for manufacturing membranes separating oxygen from air.
