Wenn auch die Herstellung haltbarer Diaphragmen für elektrolytische Zwecke in neuester Zeit grofse Fortschritte gemacht hat. so haften allen diesen Diaphragmen doch immer noch gewisse Nachtheile an. sei es in Hinsicht ihrer mechanischen Haltbarkeit, ihrer chemischen Haltbarkeit oder der Schwierigkeit bezw. der Kosten ihrer Herstellung.Albeit the production of durable diaphragms for electrolytic purposes in the newest Time has made great strides. so all these diaphragms still adhere certain disadvantages. be it in terms of their mechanical durability or their chemical properties Durability or the difficulty respectively. the cost of their manufacture.

Ein Material, welches zur
Diaphragmen in Bezug auf chemische und mechanische Haltbarkeit, sowie auf die relativen
Herstellungskosten vor den bisher benutzten sich sehr vortheilhaft auszeichnet, ist der Glimmer,
und zwar lassen sich solche Glimmerdiaphragmen ebenso für die Elektrolyse von wässerigen
Lösungen, wie für die geschmolzener Salze, sowie für stark ätzende Flüssigkeiten verwenden,
was bei anderen Diaphragmen aber wegen ihrer zu geringen chemischen bezw. mechanischen
Haltbarkeit nicht zutrifft.A material that is used for
Diaphragms in terms of chemical and mechanical durability, as well as the relative production costs, are very advantageous compared to those previously used, is mica, and such mica diaphragms can be used for the electrolysis of aqueous solutions as well as for the molten salts, as well as for strong Use corrosive liquids, which is the case with other diaphragms because of their inadequate chemical properties. mechanical durability does not apply.
Um eine Glimmerplatte, die an und für sich für Flüssigkeiten bekanntlich nicht durchlässig ist und auch dem elektrischen Strom keinen Durchlais bietet, für Diaphragmenzwecke geeignet zu machen, muls sie mit kleinen, möglichst zahlreichen, in nahen und am besten gleichmäfsigen Abständen von einander stehenden Löchern versehen werden, die dann auf der Glimmerplatte die Maschen eines Netzes oder Gewebes vertreten. Es hat sich gezeigt, dal's es mit geeigneten maschinellen Einrichtungen leicht ist, solche Löcher sogar auf einer gröfseren Anzahl von dünnen Glimmerplatten zugleich, ohne dafs diese an den Durchlöcherungsstellen splittern oder sonst in ihrer Cohärenz Schaden erleiden, durch eine einmalige und schnelle Manipulation, wie Stanzen, anzubringen. Eine so hergerichtete Glimmerplatte hat weder an ihrer Festigkeit, noch an ihrer Elasticität verloren und leistet, in einen passenden Rahmen gespannt, als elektrolytisches Diaphragma Vorzügliches.Around a mica plate, which in and of itself is known to be impermeable to liquids is suitable for diaphragm purposes and also offers no passage for the electric current to do it, muls them with small ones, as numerous as possible, in the near and best uniform distances from each other standing holes are provided, which then open the mica plate represent the meshes of a net or fabric. It has shown, as it is easy with suitable mechanical equipment to even make such holes on one larger number of thin mica plates at the same time, without these at the perforation points splinter or otherwise suffer damage in their coherence, by a one-time and quick manipulation such as punching to attach. A mica plate prepared in this way has neither its strength nor its strength lost its elasticity and, when stretched in a suitable framework, performs as electrolytic Diaphragm excellent.
In Bezug auf die Durchlässigkeit für den Elektrolyten und — infolge der geringen Dicke ihrer Löcher — auch in Bezug auf geringen elektrischen Widerstand steht sie den aus anderem Material hergestellten Diaphragmen mindestens gleich; in Bezug auf Festigkeit bei grol'ser Dünne der Platte und in Bezug auf Elasticität ist sie allen anderen bisher bekannten Diaphragmen bedeutend überlegen.In terms of permeability to the electrolyte and - due to the low Thickness of its holes - also with regard to low electrical resistance, it stands the Diaphragms made from a different material are at least the same; in terms of strength the greater thinness of the plate and in terms of elasticity it is known to all others so far Significantly superior to diaphragms.

should be, must have a comparatively great thickness, and consequently also offer greater resistance to the electric current. Their production is also much more laborious and therefore expensive, not least because of this.
