Investigation on Supersonic Gas Flow Coupled With an Inductive Low-Pressure Plasma Used for the Synthesis of Sofc Material

Deposition of ZnO thin films from aqueous solution in a low power plasma reactor

“…In the first investigations, the horizontal plasma reactor consisted of a Pyrex tube (length: 560 mm and internal diameter : 46 mm) equipped with a convergent nozzle (7 mm in diameter at the exit) [18][19][20][21][22][23]. In this work, the orientation of the tube was modified to become a vertical plasma reactor.…”

“…Its principle of operation is very simple and flexible: an aqueous solution of nitrates is injected into a low power plasma reactor under a spray form, which leads to the formation of the oxide coating onto the surface of a substrate. In the past, this plasma process was investigated for the deposition of the electrodes of Solid Oxide Fuel Cells (SOFC) [17][18][19]. This plasma process was also employed for the deposition of innovative Thermal Barrier Coatings (TBC) exhibiting an original nano/microstructure [20].…”

Electrochemical studies on Sr doped LaMnO3 and LaCoO3 layers synthesised in a low-pressure plasma reactor equipped with a convergent nozzle

“…The deposit thus grew into a layer 40-50 lm h )1 thick. Because of the convergent nozzle, over-pressure waves were created, leading to the acceleration of the gases and particles circulating in the reactor [8][9][10]. The high velocity of the micrometric particles (80 m s )1 measured by Laser Doppler Anemometry at the exit of the nozzle) led to a very strong adherence of the cathode layer on the YSZ substrate.…”

“…Nevertheless, thermodynamics shows that undesirable phases (La 2 O 3 , La(OH) 3 , Mn 3 O 4 ...) could appear at high temperature (T > 2000 K) [5][6][7]. In order to produce SOFC high quality cathodes, a low-pressure plasma reactor has been developed in our laboratory [8][9][10].…”

“…Recent work allowed optimisation of the process by investigating different synthesis parameters [8][9][10]. Scanning Electron Microscopy (SEM) was performed to study the quality and the structure of the layers deposited.…”
