The efficient flame assisted spray pyrolysis method by using flash boiling atomization under low-pressure condition was proposed. Methane-oxygen premixed flame was utilized as the heat source and the precursor water solution was sprayed at low-pressure field. The precursor water spray, which injected in low-pressure field, was secondary-atomized by flash boiling atomization. In order to investigate the effects of flash boiling atomization on the nanosized particle synthesis, the flashing spray was visualized, measured and analyzed by the Mie scattering method and PDA measurement. Furthermore, ZnO nanoparticles synthesized for investigating the effects of flash boiling atomization on the generated particles. It was found that the spray droplet was well atomized and dispersed when flash boiling occurred. In addition the size of synthesized particles became smaller under the conditions of high temperature and of low pressure.
