    摘要: An electrode for fusion electrolysis comprising an upper portion (5) of metal and a replaceable lower portion (6) of self-consuming or of slowly self-consuming material which are interconnected by a screw-nipple (1) or the like, whereby the upper portion may have a cooling device with a feed duct (2) and a return duct (3) and the upper portion (5) has at least partially and preferably in its lower region a protective covering, whereby this covering is a detachably surmounted sheath (4) of mechanically resistant material, which is electrically conductive. The sheath can be sub-divided into individual segments, while the design of screw-mounted units with internal recesses for the acceptance of resilient, electrically conductive materials reveals especially favorable properties.

    摘要: A metal electrode with an active cover layer for electrochemical purposes which cover layer includes metal platinates, metal palladates, or the like, and metal palladates and comprises, as embedding substances compounds of the type Ba (M.sub.x Ti.sub.1.sub.-x)O.sub.3 where M is a platinum metal. The latter may be used alone or in combination with other additives and does not impair on the one hand the effectiveness of the active materials and is on the other hand, when exposed to an electrolytic bath, location in chemically resistant without showing complete inactivity and, thus, increase the current yield of the anode.
