Single‐phase ZnO nanoparticles were successfully prepared by solid–liquid reaction ball milling assisted by ultrasonic wave. The samples were characterized by X‐ray diffraction and transmission electron microscopy. By the comparison of the as‐milled products with and without the help of ultrasonic wave, it is found that ultrasonic wave is a key factor promoting the transformation from Zn(OH) 2 to ZnO. Based on hot‐spot theory, the formation mechanism of the single‐phase ZnO nanoparticles under ultrasonic wave assistance is determined.
