Notes:
To obtain a mass production of nanocrystalline ZnO powders, equipment that combines theconventional self-sustaining combustion process (SCP) with the ultrasonic spraying combustionmethod (USCM) were applied. The droplet was sprayed into the reaction zone of the furnace tocarry out USCM that produces softly agglomerated crystalline ZnO particle with spherical shape.It was confirmed that the ZnO powder was prepared from ultrasonic spraying combustion methodhaving smaller primary particle size, spherical shape with weak agglomeration and larger specificsurface area than from conventional self-sustaining combustion method. Synthesizednanocrystalline ZnO powders have primary particle size in a range of 20∼30 nm, and specificsurface area of about 20 m2/g under the optimum ultrasonic spray conditions
