Definitions
- the invention relates to an anode for aqueous electrolysis, consisting of a framework which is resistant to the electrolyte and the electrolysis products, a porous substrate containing titanium connected to the framework and electrochemically active substances which are distributed in the pores of the substrate, characterized in that porous titanium-containing substrate is produced from a powder mixture of titanium with nickel or chromium, the proportion of nickel or chromium being 2 to 20% by weight.
- the passivation rate of various anodes that do not have coatings with electrochemically active substances is measured in 20% sulfuric acid at room temperature and a current density of 0.2 kA / m2. Passivation is indicated by an increase in cell voltage to 10 V.
