Abstract :
Zn powders were milled by stainless steel balls in the aqueous solution whose PH value were adjusted to 3, 7, and 11, respectively. Zn(OH)2 and ZnO powders could be synthesized via this novel solid–liquid ball milling method. The compositions and the microstructures of the as-milled products were characterized by X-ray diffraction and SEM, respectively. The experimental results showed that the higher PH value is helpful to accelerate the reaction between Zn and H2O. ZnO is the preferential product in the neutral and alkaline solutions. As a preferential product, a large number of ZnO could be obtained in the neutral and alkaline solutions after reaction. Finally, the phase transformation regularities of the as-milled products were also discussed.
