Controlling thermal expansion and phase transitions in CaSrMnO by Sr-content.

Perovskite oxides of the general formula ABO, with A and B being metal cations, present themselves in various crystal structures that originate from a distorted ideal cubic perovskite. Understanding how composition, temperature, atmosphere and reduction extent of these non-stoichiometric redox materials induce structural changes on an atomic, as well as macroscopic, level is crucial to transfer newly developed materials to industrial scale applications in the redox-based energy conversion sector. Herein, CaSrMnO ( ∈ [0,0.

Single-step fabrication of nanolamellar structured oxide ceramic coatings by metal-organic chemical vapor deposition.

Oxide ceramic coatings in the system Y2O3-Al2O3-ZrO2 were fabricated in laboratory scale by using a MOCVD unit. A hot wall reactor was used along with different precursor feeding systems. Most experiments were carried out by using powder flash evaporation including a screw feeder for precursor powder delivery.
