| 摘 要： | 采用扫描电镜（SEM）研究在碱性电解液中通过恒电位沉积得到的铅粉。结果表明：铅晶体的形状主要取决于电沉积的过电位。通过欧姆控制步骤可以得到规则晶体。通过扩散控制得到的枝晶形状和电沉积的过电位有关系。不断增加的过电位导致枝晶的分枝从原始类型变成发达的三级分枝。基于该电解液属于络合铅电解液，解释具有强烈的（111）择优取向的枝晶分枝的形成原因。

| Abstract: | Lead powder obtained by potentiostatic electrodeposition from alkaline electrolyte, based on hydroxide ions, was investigated. The shape of lead crystals strongly depends on overpotentials of electrodeposition. The regular crystals are formed in the ohmic control. The shape of dendrites formed in the control of diffusion has a function of overpotentials of the electrodeposition. Increasing overpotential leads to branching of dendrites from primary type to those with developed tertiary branches. Formation of the very branchy dendrites of the strong （111） preferred orientation is explained on the basis of the affiliation of this electrolyte to the group of the complex Pb electrolytes. |
