The Preparation of Electrolytic Manganese from MnCl_2 System with PbO_2/Ti as Anode(Ⅰ)——Preparation of PbO_2/Ti Anode and its Characteristics

本篇报道可用于氯化锰体系制备电解金属锰的新型钛基二氧化铅电极的研制方法。该电极具有阳极电位低、界面电阻小、PbO_2沉积层致密无针孔、边缘效应小的优点。对PbO_2镀层进行了扫描电子显微分析和X射线分析。

A method for developing a new type PbO_2/Ti electrode is reported in this paper.The elec- trode can be used as an anode to prepare electrolytic manganese from MnCl_2 system.It is characterized by such strong points as low anode potential,small interface resistance,compactness of PbO_2 depositing coating,and small edge effect,etc.The PbO_2 coating is analyzed by scanning electron microscopy and X- ray.
