Abstract: Wet high-energy ball milling was carried out by a planetary ball mill to study the changes of morphology, size and decomposition activation energy of basic zinc carbonate particles under different ball milling conditions. The product was characterized by SEM, XRD, TG and DSC. The results show that the ball milling time has a significant effect on the particle size and thermal decomposition activation energy of basic zinc carbonate. The ball mass ratio is 10 ∶1 and the rotation speed is 200 r/min, which account for the material quality. Under the action of 64% ethanol control agent, after 6 h of high-energy ball milling, the particle size is changed from 50 μm in particle size to 50 nm in isometric shape. When ball milling to 24 h, the particle size does not shrink further. The decomposition activation energy is reduced from 138.0 kJ·mol^-1 to 112.4 kJ·mol^-1 after ball milling for 24 h, and the thermal decomposition temperature is pushed forward by 14.8 ℃.
