Abstract: A gas-generating metal electrode comprises hollow profiled sections arranged parallel to one another in a horizontal plane and interconnected by a current distributor. The faces of the profiled sections facing the counterelectrode are curved, the curvature being greater at the sides than in the centre. At the top, the profiled section is terminated by two side faces emerging tangentially from the curvature. The electrode is suitable as anode for chlorine-alkali electrolysis amalgam cells.

Abstract: 1. A process for manufacturing an electrode consisting of an electrically conducting support structure bearing an electromechanically active boron-containing nickel layer deposited thereon by electroless deposition from a bath of a nickel(II) salt and a complexing agent by reduction with sodium boranate, wherein said bath contains a molar ratio of complexing agent : nickel salt of from 80 to 200, a molar ratio of sodium boranate : nickel salt of from 0.7 to 4.0, from 10 to 400 mmol/l of a hydroxide of sodium, potassium or an alkaline earth metal which is more strongly basic than ammonia, and from 10 to 80 mmol/l of nickel salt.

Abstract: In an electrode suitable for electrolysis of aqueous sodium chloride or potassium chloride solutions, at least the outer layer contains spinels, specifically a mixture of the individual spinels of iron and of cobalt, the weight ratio of iron spinels: cobalt spinels being from 30:70 to 90:10. The electrodes are produced by applying a powder mixture of iron spinel and cobalt spinel to a substrate by a plasma spraying process wherein argon is used as the plasma gas and the spraying energy is from 6 to 30 kW.
