Abstract Spray pyrolysis is a low-cost method of depositing thin films and is economically more attractive than other methods that have been used to produce stable CuInS2 thin films. The electrical, optical and structural properties of the films, as prepared, are presented together with their evolution and with a variation of some fabrication ...

Zirconia coatings by spray pyrolysis
Surface and Coatings Technology, 1997Abstract Zirconia coatings were obtained with the spray pyrolysis process, using a precursor solution of zirconium n-propoxide in 1-propanol. An investigation was undertaken into the influence of carrier gas (air, He, N2 and Ar), temperature (450 and 600 °C), time (1 and 2 h) and substrate composition (borosilicate glass, alumina, stainless steel and

Spray pyrolysis of YBCO precursors
Journal of Materials Research, 1994Acetate, nitrate, and oxalate precursors for YBCO have been spray pyrolyzed under different conditions. Shelled and nonhollow microparticles were obtained from acetate and nitrate precursors, while nonhollow agglomerates were obtained from the oxalate suspension.

Evaluation of Spray Performance of Pyrolysis Oil
Volume 3: Coal, Biomass, Hydrogen, and Alternative Fuels; Cycle Innovations; Electric Power; Industrial and Cogeneration; Organic Rankine Cycle Power Systems, 2019Abstract Pyrolysis oil has become an important subject of research as it is considered to be a potential environmentally friendly and cheap alternative to conventional fossil fuels. Unfortunately, due to the significant differences of the chemical and physical properties of pyrolysis oil than that of fossil fuels, the deployment of ...

Modelling of nanoparticle formation during spray pyrolysis
Nanotechnology, 2006A mathematical model for the evaporation of micro- and nano-sized solution droplets is developed. This model is used to predict whether the particles produced by spray drying and pyrolysis are fully filled or hollow. The model includes the non-continuum effects on the droplet evaporation.

Flame spray pyrolysis (FSP) has been applied for the production of powders industrially. FSP allows production of powders with controlled characteristics at a high rate. In addition to the process parameters, several other factors are crucial for nanoparticle production.

Spray Drying, Spray Pyrolysis and Spray Freeze Drying
2010In 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, 1987The 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 ...

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 ...

CuInS2 films prepared by spray pyrolysis
Solar Energy Materials, 1979Abstract 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,
