Abstract
Zinc powders were electrodeposited from ZnCl 2 baths with containing suspension of unsoluble particles such as graphite, PbO 2,SnO 2,TiO 2, SiO 2 etc.. The structure, morphology and corrosion behavior of zinc powder were analyzed. SEM results showed that the dendritic growth of zinc can be inhibited by applying the suspension method. Suspension of PbO 2, SnO 2, TiO 2, SiO 2 and In 2O 3 could greatly improve the corrosion protection of zinc powder in 5 mol/L KOH. In addition, fractal theory is employed to further explain the results.
