电解MnO_2(EMD)新工艺——掺Ni的Ti基不溶性阳极的研究

Research of Penetrated Ni-Ti Anode used of production of Electrolytic MnO2

本文报道了在钛基电极中经高温扩散掺镍以制得的掺 Ni-Ti 基不溶性阳极,用于电解 MnO_2(EMD)生产工艺中,其性能明显优于目前在工业上使用的纯钛阳极。此类电极的实验室数据能使阳极电流密度 i.d 提高至100A/m^2,槽电压稳定在3.0±0.2V,可长期使用不致钝化。为进一步工业化试验提供了有力数据。

This paper reports a new kind of penetrated Ni—Ti Anode,used for the productim of electrolytic MnO_2.This anode is Superior to pure titanium anode for it suitabilily and stability high for electricity density (i、d),just to 100A/m^2,Further research of industry scale is warranted.
