Zinc oxide(ZnO) powders were synthesized via a hydrothermal process to control the particle morphology. Zinc hydroxide (Zn(OH) 2 ) was used as precursor to avoid the influence of unnecessary anions. The sodium oleate (SO) and polyethylene glycol (PEG) were used as additives to control the particle growth through the surface adsorption. ZnO particles synthesized with SO were rod-shaped with a node. ZnO particles synthesized using with PEG were rod-shaped and the morphology was changed with change of pH in the reaction solution. The size of the ZnO precipitated on the substrate under the strong magnetic field of 12 T was decreased. Key Words : ZnO, hydrothermal process, additive, strong magnetic field
