Bei dem vorliegenden Verfahren werden Silberelektroden unter Verwendung von Chlorsilber dadurch hergestellt, dafs man in bekannter Weise geschmolzenes Chlorsilber in oder um einen geeignet gestalteten Elektrodenträger giefst, und sodann das Chlor auf elektrolytischem Wege aus der Elektrode entfernt. Da jedoch die unter alleiniger Verwendung, von Chlorsilber hergestellten Elektroden nicht genügende Porosität besitzen, wird bei dem vorliegenden Verfahren dem geschmolzenen Chlorsilber Chlorblei hinzugesetzt. Letzteres hat gegenüber anderen, namentlich bei Herstellung poröser Bleielektroden benutzten, später entfernbaren Zusatzmitteln den Vortheil, dafs nach der Entfernung des Chlors aus der Elektrode und dem darauf folgenden Herauslösen des Bleies das zurückbleibende Silber eine fest zusammenhängende dauerhafte Masse bildet.In the present method, silver electrodes are made using chlorine silver produced by pouring molten silver chlorine in a known manner into or around a suitably designed electrode carrier, and then electrolytically pouring the chlorine Paths removed from the electrode. However, since the under sole use, Electrodes made from chlorine silver do not have sufficient porosity In the present process, lead chlorine was added to the molten silver chlorine. The latter has later compared to others, especially those used in the manufacture of porous lead electrodes removable additives the advantage that after the chlorine has been removed from the electrode and then dissolved out of the lead, the remaining silver forms a firmly coherent, permanent mass.
Bei den Versuchen hat sich ein Zusatz von 15 bis 20 pCt. Chlorblei zum Chlorsilber als besonders günstig erwiesen. Die mit solcher Mischung gegossenen Platten werden in Alkalilauge zunächst zur Entfernung des Säureradikals der reducirenden Wirkung des elektrischen Stromes ausgesetzt und hierauf zur Entfernung des Bleies in neuer Lauge als Anoden der Wirkung des elektrischen Stromes unterworfen, wobei das Blei gelöst und auf die Kathode niedergeschlagen wird, während das Silber in Oxyd übergeführt wird.In the tests, an addition of 15 to 20 pCt. Chlorine lead to chlorine silver as proved particularly favorable. The panels cast with such a mixture are immersed in alkali first to remove the acid radical of the reducing effect of the electric Exposed to the current and then to remove the lead in new lye as the anode Subjected to action of electric current, the lead being dissolved and applied to the cathode is precipitated while the silver is converted into oxide.
In einem weiteren Alkalibad können die Platten mit Hülfe des elektrischen Stromes wieder zu reinem Silber reducirt werden, oder man baut sie im oxydirten Zustand in Elemente ein.In another alkali bath, the plates can be heated with the aid of an electric current be reduced again to pure silver, or they are built into elements in the oxidized state a.
