一种电沉积制备细铅粉的方法
摘要：
本发明涉及一种电沉积制备细铅粉的方法，属于新材料制备技术领域。首先配置电解液：将可溶性铅盐、络合剂、缓冲剂、分散剂和水混合均匀后配置成电解液；电沉积过程：以金属铅为阳极，钛为阴极，在控制电解液温度为20~80℃、阴极电流密度为200~500mA/cm2条件下，在电解液中超声波辅助电沉积50~200min，即能在阴极得到细铅粉。本方法工艺操作简单，细铅粉经过一次电化学共沉积即可形成。
摘要（英）：

Belonging to the technical field of new material preparation, the invention relates to a method for preparation of fine lead powder by electrodeposition. The method includes: (1) preparation of an electrolyte solution: mixing a soluble lead salt, a complexing agent, a buffering agent, a dispersing agent and water evenly to obtain the electrolyte solution; and (2) an electrodeposition process: taking metal lead as the anode, and adopting titanium as the cathode, and under the conditions of controlling the electrolyte solution temperature at 20-80DEG C and the cathodic current density at 200-500mA/cm<2>, conducting ultrasonic assisted electrodeposition in the electrolyte solution for 50-200min, thus obtaining fine lead powder at the cathode. The method provided by the invention is simple in technological operation, and the fine lead powder can be formed by one electrochemical co-deposition.
