SOLUTION SPRAY PROCESS FOR PREPARATION OF INORGANIC NANOSIZED PARTICLES USING CO-PRECIPITATION TECHNIQUE IN MICELLAR MODE

摘要

1. Dissolving the precursor and precipitator independently in solvent to form concentrated solutions at specified strength. 2. Mixing the appropriate surfactant either with precursor or precipitator. North Maharashtra University, Jalgaon 3. Spraying these solutions independently and simultaneously in co-precipitation reactor to form the reaction zone in flowing thin film form. 4. Controlling the individual spray to maintain fan pattern in flowing reaction film. 5. Controlling input flow rates and discharge rates for providing specific residence time/ holding time. 6. Filtering the resultant reaction mixture, containing nanosized product, through fine mesh filter. 7. Washing with solvent to remove soluble by-products (Salt) formed during the reaction. 8. Low temperature vacuum drying of nanoparticles to eliminate residual traces of solvent.
