Description
Verfahren zur Herstellung dünnster dielektrischer bzw. dünnster leitender Schichten, insbesondere für Kondensatoren und Kabel Die vornehmste Aufgabe der Kondensatorentechnik besteht in der Herstellung dünnster, dielektrisch hochwertiger Schichten sowie dünnster leitender metallischer Beläge.Process for the production of the thinnest dielectric or thinnest conductive ones Layers, especially for capacitors and cables The most important task of capacitor technology consists in the production of the thinnest, dielectrically high-quality layers as well as the thinnest conductive metallic coverings.
Die Aufgabe, dünne leitende Schichten getrennt durch dünne nichtleitende Schichten zu erzeugen, benutzt eine an sich bekannte Erscheinung, daß chemische Niederschlagsreaktionen in Gallerten in rhythmischer Form als Ringe oder parallele Schichten auftreten; nach R. L i e s e g a n g, der dies zuerst beobachtete, bezeichnet man diese Erscheinung als Liesegangsche Ringe.The task of making thin conductive layers separated by thin non-conductive layers Generating layers uses a phenomenon known per se, that of chemical Precipitation reactions in jelly in rhythmic form as rings or parallel Layers occur; named after R. L i e s e g a n g, who first observed this one this phenomenon as Liesegang's rings.
Zur Herstellung eines IsolierköTpers mit in geringem Abstand voneinander eingelagerten, dünnen, elektrisch leitenden Schichten werden nun erfindungsgemäß in einem porösen Isolierkörper durch chemische Fällungsreaktionen nach Art der Liesegangschen Ringe Schichten erzeugt und diese anschließend in leitende Schichten umgewandelt.For the production of an insulating body with a small distance from each other embedded, thin, electrically conductive layers are now according to the invention in a porous insulating body by chemical precipitation reactions like the Liesegangschen Rings created layers and then converted them into conductive layers.
Die Porosität des Ausgangsisolierkörpers soll möglichst klein sein, d. h. etwa einem nicht dicht gebrannten keramischen Körper entsprechen.The porosity of the initial insulating body should be as small as possible, d. H. correspond approximately to a ceramic body which has not been fired tightly.
Die Umwandlung der gefällten Schichten in leitende Schichten kann durch thermische Zersetzung und/oder Reduktion erfolgen.The conversion of the precipitated layers into conductive layers can take place by thermal decomposition and / or reduction.
So wird, z. B. ein poröser Zementkörper, vorzugsweise mit Rutil, gebildet und z. B. mit Ammoniumchlorid oder Kupferchlorid oder Eisenchlorid getränkt. Danach wird der Keramikkörper in eine Silbernitratlösung oder Ferrocyanidlösung getaucht, woraufhin sich in bestimmten Abständen von der Ausgangsfläche Schichten von Silberchlorid oder Kupferferrocyanid oder Berlinerblau ausscheiden, die dann durch Reduktion oder thermische Zersetzung in metallische Beläge übergeführt werden.So, z. B. a porous cement body, preferably with rutile, formed and Z. B. soaked with ammonium chloride or copper chloride or iron chloride. Thereafter the ceramic body is immersed in a silver nitrate solution or ferrocyanide solution, whereupon layers of silver chloride form at certain distances from the initial surface or copper ferrocyanide or Prussian blue excrete, which then by reduction or thermal decomposition can be converted into metallic deposits.
Bei einem zylindrischen Keramikkörper wird man die Silbernitrat- oder Ferrocyanidlösung von der inneren. oder äußeren Fläche des Zylinders aus diffundieren lassen, so daß sich konzentrische Ringe bilden. Der gegenseitige Abstand der Reaktionsschichten wird von den Konzentrationen der Reagenzien bestimmt.In the case of a cylindrical ceramic body, one will use the silver nitrate or Ferrocyanide solution from the inner. or diffuse outer surface of the cylinder from so that concentric rings are formed. The mutual spacing of the reaction layers is determined by the concentrations of the reagents.
Auf jeder Stirnfläche des Isolierkörpers werden die leitenden Schichten abwechselnd isoliert und kontaktiert, derart, d'aß die eine Hälfte der Schichten die eine Belegung und die andere Hälfte die andere Belegung des Kondensators, darstellen, der sich infolge der geringen Abstände der leitenden Schichten voneinander durch große Volumenkapazität auszeichnet. Man kann jedoch: auch jede Schicht einzeln als Stromleiter benutzen, so daß sich eine Koaxialleitung mit um die Achse koaxial angeordneten, voneinander isolierten Einzelleitern ergibt.The conductive layers are on each end face of the insulating body alternately isolated and contacted, such that one half of the layers one assignment and the other half the other assignment of the capacitor, due to the small spacing between the conductive layers large volume capacity. However, you can: each layer individually as a Use current conductors so that there is a coaxial line with coaxially arranged around the axis, isolated single conductors results.
Die Schichten können auch ohne äußeren Anschluß beim Aufbau eines Kabels Verwendung finden und geben dann in bekannter Weise eine kapazitiv gesteuerte Spannungsverteilung über den gesamten Isoliermantel.The layers can also be used without an external connection when building a Cables are used and then give a capacitively controlled one in a known manner Stress distribution over the entire insulating jacket.
Die überschüssigen Ionen im Formkörper werden verdampft oder elektroos.motisch entfernt.The excess ions in the molded body are evaporated or electro-osmotic removed.
Zur Herstellung eines Formkörpers wird z. B. Rutil mit einem Bindemittel kalt zu einem Keramikkörper verformt oder in dünner Schicht auf einer Metallfolie, Glasfließ und anderes aufgetragen und abbinden gelassen.To produce a molded body, for. B. rutile with a binder cold formed into a ceramic body or in a thin layer on a metal foil, Glass floss and other things applied and left to set.
Als Bindemittel kommen übliche Zemente, Wasserglas, Zinkox5-dph.ospho,rsäure-Zement in Betracht.Usual cements, water glass, zinc oxy-dph.osphoric acid cement are used as binders into consideration.
