Ceramic Powder Synthesis by Spray Pyrolysis

Journal of the American Ceramic Society, 1993
A variety of spray pyrolysis (SP) techniques have been developed to directly produce ceramic powders from solutions. This paper reviews the current status of these processes in terms of the process parameters that enable the formation of particles with controlled morphology and composition.

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.

Aerosol Spray Pyrolysis Synthesis Techniques

1994
Aerosol techniques provide a convenient method for generation of small particles of high purity and a wide range of chemical formulations. Here we will emphasis the method of aerosol spray pyrolysis wherein solutions of precursor salts are nebulized and then dried and pyrolyzed in a furnace reactor.

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.

Spray pyrolysis of CuInSe2 thin films

Solar Energy Materials, 1980
Abstract The structural, electrical and optical properties of thin films of CuInSe 2 prepared by spray pyrolysis are described. The films were of the sphalerite or chalcopyrite structure, depending on the substrate temperature. Some effects of post-deposition heat-treatment are also presented.

Ultrasonic spray pyrolysis of TiO2 nanoparticles

Nanostructured Materials, 1997
Synthesis of ultrafine spherical TiO2 particles was achieved by using ultrasonic spray pyrolysis and nanoparticles of TiO2 (approximate to 2.5nm) as a precursor. The size distribution and morphology of TiO2 particles obtained after ultrasonic spray pyrolysis were characterized by SEM and STM.

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 ...

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.

Deposition of CdTe by spray pyrolysis

Thin Solid Films, 1982
Abstract We report the spray pyrolysis of thin films of CdTe which show promise as a base material for solar cell applications. The films predominately show a zinc blende structure and appear to be intrinsic. Microprobe analysis indicates an excess of cadmium but this is not detectable by X-ray diffraction or from electrical conduction measurements ...
