SU484893A1 - Anode material for electrolytic production of manganese dioxide - Google Patents

Description

This invention relates to anode materials for the electrolytic production of manganese dioxide. Known anode material for fugging manganese dioxide by electrolysis, containing titanium. However, this anode material is dissiviated when the current density 2 is higher than 0.5 a / dm. In order to eliminate the anode passivation at elevated current densities (2 u, 5 a / dy;), an anode material containing tan The following components were introduced in MartanP in the first type of alloy with the following ratio; with a manganese content of more than 16 wt.% susceptible to intense corrosion Example. Manganese dioxide is precipitated at the anode of the composition, wt.%: Manganese9 Titus Else The initial concentration of manganese is VO g / n, final 2O g / n, Kato is lead. At anode current density of 1 A / dm, the MitO current output is 99.5%. According to the data of spectral analysis, there are no admixtures of arsenic, iron, aluminum, chromium and {nankel). Calcium impurities are / are hundredths of a percent, lead and ma1; nor are percent. The titanium iC alloy used for the anode with manganese of this composition makes it possible to eliminate the anode passivation. of the invention Anode material for aleptic palucine manganese dioxide material containing itan, characterized in that. - - - -. 1.
