摘要： The anode is particularly designed for use at anodic densities D.sub.A greater than 10 kA/m.sup.2, and comprises substantially horizontally extending coated anode segments having a clear spacing of at least 1.5 mm from each other and upwardly extending lateral surfaces. Each segment has an active coated part higher than 5 mm and not exceeding 20 mm, measured from the horizontal undersurface of the anode. The actual active surface of the parts, up to heights of 5 mm, 7.5 mm, 10 mm and 15 mm, respectively, exceeds at least 2.5, 3.33, 4 and 4.7 times, respectively, the projected anode area which latter is the total area bounded by the periphery of the anode. At least half the actual active surface extends upwardly relative to the horizontal base area of the anode.

摘要： A valve metal anode, for electrolytical processes, having an electron-active covering layer, comprises electron-activating substances, counteracting passivation of the anode, anchored in a sintered porous carrier layer of valve metal. The carrier layer which is sintered onto the cleaned valve metal base may consist of a powder of the same metal or of the crystallographically similar metal. The infusion of the active substances into the carrier layer can be accomplished by impregnating and drying or baking the active substances, by precipitating them from the vapor phase, galvanically, or from the gaseous phase. The active substances may also be ingredients of the sinter mixture.
