摘要
Mercury free zinc alloy powder were electrodeposited from alkaline solution. Additives containing lead, indium or bismuth were added in the electrolyte and zinc powders with corresponding compositions were obtained. The relations between adding amounts of additives and the contents of corresponding compositions in zinc powder are not linear. Aluminum and calcium cannot be co deposited with zinc. Electrodeposition effectively reduced the contents of harmful impurities. Gas evolution of electrodeposited Zn Pb In Bi alloy powder was less than that of atomized mercury free alloy powder.
