Scale up of ultrasonic spray pyrolysis process for nano-powder production - Part I

Nanostructured materials and their application have been one of main research topics in the last decades. Various nanomaterials and endless application of them is known today. On the other hand, industrial application of nanomaterials is still challenged with limited offer of methods suitable for big scale nanomaterials production, especially when it comes to nanomaterials with target morphology and complex composition. In this paper is presented a report on scale up of Ultrasonic Spray Pyrolysis (USP) process. The USP as the nanoparticle production method is relatively inexpensive and quite versatile technique based on an aerosol process to produce fine metallic, oxidic, composite nanoparticles of precisely controlled morphology and defined chemical compositions from water solution using different metal salts and their mixtures [1-4].
