Description

Verfahren zur Herstellung von mangannitrathaltigen Depolarisationselektroden Es ist bereits vorgeschlagen «-orden, bei der Herstellung von positiven Elektroden für elektrische Elemente dem aus Braunstein bestehenden Elektrodenmaterial Salpetersäure zuzusetzen. Dabei bilden sich geringe Mengen Mangannitrat.Process for the production of depolarization electrodes containing manganese nitrate It has already been proposed «-order in the manufacture of positive electrodes for electrical elements the electrode material consisting of manganese dioxide nitric acid to add. Small amounts of manganese nitrate are formed in the process.

Gemäß der Erfindung setzt man den positiven Elektroden für elektrische Elemente jedoch wesentlich größere Mengen Mangannitrat zu, und zwar zu dem Zweck, eine Verfestigung der Elektroden herbeizuführen. Um eine ausreichende Verfestigung zu erzielen, ist bei Verwendung bekannter Mischungen von etwa 6o bis 8o Teilen pulverisiertem Braunstein und 2o bis q.o Teilen Graphit je Kilogramm .Elektrodenmaterial nötig, etwa 5o bis Zoo ccm einer gesättigten Lösung von Mangannitrat zuzusetzen. Für je Kilogramm des verwendeten Braunsteins sind also etwa 5 bis io °/o einer gesättigten Mangannitratlösung nötig. Das mit Mangannitrat versetzte Elektrodenmaterial wird in an sich bekannter Weise durch Pressen weiterverarbeitet. Nach dem Pressen werden die Elektroden zweckmäßig bei etwa i8o° getrocknet. Die Festigkeit solcher Eelektroden ist so groß, daß es sich erübrigt, ihnen eine Schutzhülle zu geben.According to the invention, the positive electrodes are used for electrical Elements, however, much larger quantities of manganese nitrate, for the purpose of to bring about a solidification of the electrodes. To have sufficient solidification is to be achieved using known mixtures of about 6o to 8o parts powdered Brownstone and 2o to q.o parts of graphite per kilogram. Electrode material required, add about 50 to zoo cc of a saturated solution of manganese nitrate. For each Kilograms of the brownstone used are thus about 5 to 10 per cent of a saturated one Manganese nitrate solution necessary. The electrode material mixed with manganese nitrate is further processed in a manner known per se by pressing. After pressing will be the electrodes are expediently dried at about 180 °. The strength of such electrodes is so big that there is no need to put a protective cover on them.

Anstatt das Mangannitr at dem Elektr odenmaterial zuzusetzen, kann man es auch in ihm selbst .durch Zusatz eines Gemisches von Salpetersäure und Salzsäure erzeugen. Die gleichzeitige Verwendung von Salzsäure ist notwendig, weil sich nur in diesem Falle eine ausreichende Menge Mangannitrat bildet. Für je i kg Elektrodenmaterial verwendet man zweckmäßig ioo his Zoo cctn konzentrierte Salpetersäure, der 5 bis io ccrn Salzsäure zugesetzt wird. Die weitere Verarbeitung ist die gleiche wie bei einem Material, dem Mangannitrat zugesetzt ist.Instead of adding the manganese nitrate to the electrode material, can you can do it in yourself by adding a mixture of nitric acid and hydrochloric acid produce. The simultaneous use of hydrochloric acid is necessary because only in this case forms a sufficient amount of manganese nitrate. For every 1 kg of electrode material it is expedient to use concentrated nitric acid, which is 5 to io ccrn hydrochloric acid is added. Further processing is the same as for a material to which manganese nitrate is added.
