Fabrication of Y2O3-doped BaZrO3 thin films by electrostatic spray deposition

Behavior of Ytterbium in Calcium and Strontium Zirconate Matrices

“…Fabrication of these compounds in thin film forms has been one of the objectives of the recent research activities. [11][12][13][14] Proton conduction of yttria doped barium zirconate, both in bulk and sputtered thin film forms was presented demonstrated by Pornprasertsuk et al 11 They also demonstrated the use of this compound for use in protonic ceramic fuel cell (PCFC) application. Somroop et al showed the deposition of yttria doped barium zirconate in thin film form by using electrostatic spray deposition (ESD) technique 12 Use of pulsed laser deposition for making the thin films of BaCe 0.9 Y 0.1 O 3-δ was demonstrated by Higuchia et al 13 This team measured the lattice deformation in the thin films also.…”

Preparation of gadolinium doped barium cerate thin films by spray pyrolysis method with a possible view to deploy it in proton conducting SOFCs was studied by Dubala et al 14 Many, recent review articles have provided the detailed account of the developments made in these materials in bulk and membrane forms for various applications.…”

Comparative Study of BaY0.1Zr0.9O3-δProtective Layers Deposited to BaY0.1Ce0.9O3-δMembrane Using Ultrasonic Spray Pyrolysis and Magnetron Sputtering Methods

“…Bi et al prepared well-conductive BaCe 0.8 Y 0.2 O 3-δ membranes with BaZr 0.7 Pr 0.1 Y 0.2 O 3-δ layers on both sides of membrane using a co-pressing method of powder-based layers. 12 Much more information is available for the preparation of BaZrO 3 layers onto the relatively inert substrates, such as Al 2 O 3 , MgO or Si, using electrostatic spray deposition, 13 atmospheric plasma spray, 14 radio frequency sputtering, 15 chemical solution deposition, 16 reactive magnetron sputtering 17 and pulsed laser deposition 10,11,18 methods. However, it should be remembered that the thermochemical nature of substrate plays a particularly important role when the preparation process of protective barium zirconate layer includes thermal treatment and because of that cation interdiffusion between BZY layer and supportive BCY membrane is possible.…”

Comparative Study of BaY0.1Ce0.9O3-δ Membrane with BaY0.1Zr0.9O3-δ Protective Layers Synthesized with Spray Pyrolysis and Magnetron Sputtering Methods

“…The cerate provides the membrane with mechanical stability, and thin BZY layer works like stable chemical barrier. Thin BaZrO 3 layers with and without yttrium doping has been prepared by some authors using electrostatic spray deposition (10), reactive magnetron sputtering (11) and pulsed laser deposition (12,13). However, so far most of these layers with one exception (13) have been prepared on inert substrates and not on BCY supportive membrane, which is important aspect if we consider possible influence of supportive membrane on the membrane properties and possible influence of cation diffusion on the properties of BZY layer during thermal treatment.…”
