Description

Verfahren zur Herstellung von Isolierkörpern auf keramischem Wege Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von Isolierkörpern auf keramischem Wege, an die hohe Anforderungen hinsichtlich thermischer und elektrischer Widerstandsfähigkeit gestellt werden; dies ist besonders der Fall bei Zündkerzen, Elektroheizanlagen, Spulen, Heizplatten, Glühkörpern usw.Process for the manufacture of insulating bodies by ceramic means The invention relates to a method for producing insulating bodies on the ceramic way, to the high demands in terms of thermal and electrical Resilience to be provided; this is especially the case with spark plugs, Electric heating systems, coils, heating plates, incandescent bodies, etc.

Für derartige hochwertige Isolierkörper bevorzugt man einen Versatz, der aus Ton, Kaolin, Tonerde, Zinkoxyd und Zirkonoxyd besteht. Diese Versatzmittel haben zwar an sich hohe thermische Eigenschaften; durch die bisher verwendeten Flußmittel, wie Feldspat, Pegmatit u. dgl., wurde die Güte der Isolierkörper jedoch wieder sehr ungünstig beeinßußt; es kam z. B. häufig vor, daß die mit diesen Flußmitteln hergestellten Isolierkörper bei höheren Temperaturen und auch namentlich bei plötzlichem Temperaturwechsel Risse bekamen und sogar zersprangen. Die Verwendung von Flußmitteln ist jedoch nicht zu umgehen, wenn ein dichter, unhygro-. skopischer Scherben erzielt werden soll.An offset is preferred for such high-quality insulating bodies, which consists of clay, kaolin, alumina, zinc oxide and zirconium oxide. These offset means Although they have high thermal properties per se; due to the flux used so far, like feldspar, pegmatite and the like, however, the quality of the insulating body became very good again adversely affected; it came z. B. often before that the manufactured with these fluxes Insulating body at higher temperatures and especially in the event of sudden temperature changes Cracked and even shattered. The use of fluxes is not, however to get around when a dense, unhygro-. scopic shards to be achieved.

Zur Vermeidung dieser Nachteile und zur Erzielung von hochwertigen Isolierkörpern wird erfindungsgemäß zudem genannten Versatz, bestehend aus Ton, Kaolin, Tonerde, Zinkoxyd und Znrkonoxyd, als Flußmittel eine künstlich hergestellte Fritte benutzt. Die Verwendung künstlich hergestellter Fritten als fluß;mittelbildende Zuschläge ist zwar bei der Erzeugung porzellanartigerMassen üblich. Im vorliegenden Falle soll jedoch eine Fritte zur Anwendung kommen, welche aus.Magnesiumoxyd, Zinkoxyd und Tonerde besteht; diese Fritte wird durch nasses Vermahlen dieser Bestandteile und Brennen des Mahlgutes im Scharffeuer bis zur Sinterung hergestellt. Die Verwendung dieser Fritte als Flußmittel zu dem angegebenen Versatz verhindert das Springen und Rissigwerden von Isolierkörpern bei höheren Temperaturen und bei plötzlichem Temperaturwechsel. Der hohe Gehalt an Tonerde in dem fertigen Material erhöht die elektrische Isolierfähigkeit.To avoid these disadvantages and to achieve high quality Insulating bodies according to the invention is also mentioned offset, consisting of clay, Kaolin, clay, zinc oxide and zinc oxide, an artificially produced flux Used frit. The use of artificially produced fries as flux-forming agents Surcharges are common in the production of porcelain-like masses. In the present However, a frit made of magnesium oxide and zinc oxide should be used in the case and alumina is made; this frit is made by wet grinding these ingredients and burning the ground material in a hot fire until sintering. The usage this frit as a flux at the specified offset prevents cracking and cracking of insulating bodies at higher temperatures and with sudden Temperature change. The high content of alumina in the finished material increases the electrical insulation ability.
