Weise geschehen Die Kieselsäure wird in ein als Kathode dienendes Gefäss gegeben, während die Anode mit einem Diaphragma umgeben wird, das vorteilhaft aus Pergamentpapier bestehen kann. Beim Stromdurchgangs wandern die Säurereste durch das Diaphragma aus dem Katllodonraum in den Anodenraum, während sich die lösliche Kieselsäure durchaus nicht verändert. Proportional mit dem Herauswandern der Säurereste kann die Spannung erhöht werden, damit auch die letzten Spuren von Säure schnell entfernt werden.
Die so gewonnene Kieselsäure ist vollkommen chemisch rein und bei geeigneter Aufbewahrung haltbar. Sie besitzt ein niedriges Molekulargewicht und unterscheidet sich ausser durch ihre hohe Reinheit auch durch diese Eigenschaft vorteilhaft von der nach den üblichen Verfahren hergestellten Kieselsäure.

The way it is done The silica is placed in a vessel that serves as a cathode, while the anode is surrounded by a diaphragm, which can advantageously be made of parchment paper. When the current passes through it, the acid residues migrate through the diaphragm from the Katllodon space into the anode space, while the soluble silica does not change at all. The voltage can be increased proportionally as the acid residues migrate out, so that the last traces of acid can also be removed quickly.
The silica obtained in this way is completely chemically pure and can be kept if stored appropriately. It has a low molecular weight and, in addition to its high purity, it also differs advantageously from the silica produced by conventional processes because of this property.
