Spray pyrolysis of electrolyte interlayers for vacuum plasma-sprayed SOFC

Solid State Ionics, 2006
Abstract The effects of gadolinia-doped ceria (CGO, Ce 0.8 Gd 0.2 O 1.9− x ) and yttria-doped zirconia (8YSZ, Zr 0.92 Y 0.08 O 2− x ) interlayers prepared by spray pyrolysis between vacuum plasma-sprayed 8YSZ electrolytes (8YSZ–VPS) and screen-printed (La 0.8 Sr 0.2 ) 0.98 MnO 3 cathodes (LSM) on the power output of solid oxide fuel cells (SOFC ...

Spray Drying, Spray Pyrolysis and Spray Freeze Drying

2010
In conventional spray pyrolysis (CSP or simply SP), a solution is sprayed into a carrier gas forming small droplets; owing to the high temperature of the surrounding gas, the solvent is vaporized and the solute is precipitated on and within the droplets. If the air temperature is high enough, solute is decomposed to form final solid particles.

Spray Pyrolysis Processing of Optoelectronic Materials

Advanced Ceramic Materials, 1987
The processing of thin-film semiconducting, optical, and electronic materials by spray pyrolysis processing is reviewed. The major processing parameters, equipment, and chemical solutions utilized in the deposition of sulfides, selenides, oxides, and ternary semiconducting compounds are described in relation to the potential applications of these ...

Carbon nanotubes by nebulized spray pyrolysis

Chemical Physics Letters, 2004
Abstract The use of nebulized spray pyrolysis for the synthesis of carbon nanotubes has been investigated in detail. Multi-walled carbon nanotubes (MWNTs) with fairly uniform diameters and aligned MWNT bundles have been obtained by using solutions of organometallics such as ferrocene in hydrocarbon solvents.

Low-pressure Spray Pyrolysis

2010
Low-pressure spray pyrolysis (LPSP) has been developed by generating micrometer-sized droplets under low-pressure environment. Unlike the conventional spray pyrolysis (CSP), a variety of nanoparticles, ranging from metals, metal oxides, to composite materials can be directly formed in the LPSP process, which was considered to follow a one-droplet-to ...

FLAME SPRAY PYROLYSIS FOR SYNTHESIS OF NANOPARTICLES

Journal of Aerosol Science, 2001
Bismuth oxide is used as additive in paints and in cataphoresis, and as substitute for lead oxide in glass or porcelain. The presence of a small amount of Bi{sub 2}O{sub 3} in calcined ZnO ceramics promotes non-linear current voltage characteristics that are used in varistor production.

Ultrasonic spray pyrolysis for nanoparticles synthesis

Journal of Materials Science, 2004
This article presents new findings regarding the effects of precursor drop size and precursor concentration on product particle size and morphology in ultrasonic spray pyrolysis. Large precursor drops (diameter > 30 μm) generated by ultrasonic atomization at 120 kHz yielded particles with holes due to high solvent evaporation rate, as predicted by the ...

CuInS2 films prepared by spray pyrolysis

Solar Energy Materials, 1979
Abstract The electrical, optical and structural properties of thin films of CuInS 2 prepared by spraying a solution of Cu 2 Cl 2 , InCl 3 and thiourea onto heated glass and alumina substrates are described. The polycrystalline films produced at prescribed spraying rates and substrate temperatures were nearly stoichiometric as shown by EDAX analysis,

Spray pyrolysis of silver indium sulfides

Thin Solid Films, 1980
Abstract Two silver indium sulfide compounds, AgInS2 and AgIn5S8, were prepared by spray pyrolysis. AgInS2 always exhibited an orthorhombic structure, whereas AgIn5S8 was cubic. Electrical and optical properties of both compounds were measured.

Gold particle generation by spray pyrolysis

Advanced Materials, 1996
Phase‐pure, micrometer‐sized, spherical gold particles (see Figure) have been generated for the first time by spray pyrolysis of gold nitrate at temperatures well below the melting point of gold. The effects of reaction atmosphere, temperature, and residence time on the morphology of the final product are described.
