Kitt zur Verbindung von-Porzellankörpern nach dem Brenne.@
Bei der Herstellung und Auswahl von Kittmassen für die Verbindung eines Porzellanteiles mit einem anderen oder mit Teilen aus anderen Stoffen nach dem Brennen des Porzellans wurde bisher hauptsächlich Wert darauf gelegt, dass die Kittmassen beim Abbinden raum. beständig sind. Trotz der Verwendung solcher Kitte treten mitunter immer noch Sprengwirkungen auf, die ihre Ursachen in den verschiedenen Wärmedehnungszahlen des Kittes gegenüber den Porzellantei1en haben. Nach vorliegender Erfindung wird dieser Übelstand dadurch bekämpft, dass der Kittmasse Stoffe in geeigneter Menge in körniger oder

Porzellan. Näherungsweise kann die eintretende Verbesserung rechnerisch beurteilt werden.
Die bekannten Kitte haben alle eine höhere Wärmedehnungszahl als Porzellan. In erster
Linie kommt Zement in Betracht, dessen kubische Wärmedehnungszahl ist : a ==4-2. 10 während für Porzellan a = o't). ioS angenommen werden kann. Ein Stoff mit geringerer

EMI1.3
Die Wärmedehnungszahl hat bei dieser Mischung also den gleichen Wert wie bei Porzellan. Sprengwirkungen sind bei Erwärmung der gekitteten Teile in diesem Falle ganz ausgeschlossen. Es ist nicht nötig, dass die Wärmedehnungen genau übereinstimmen ; man kann sich in der Praxis damit begnügen, auf dem angedeuteten Wege die Wärmedehnung von Porzellan und abgebundenem Kitt einander zu näheln.

Putty for connecting porcelain bodies after firing. @
In the manufacture and selection of putty compounds for the connection of one porcelain part with another or with parts made from other materials after the porcelain has been fired, the main emphasis has been on the fact that the putty compounds have room during setting. are persistent. Despite the use of such putties, explosive effects sometimes still occur, which are due to the different coefficients of thermal expansion of the putty compared to the porcelain parts. According to the present invention, this deficiency is combated by the fact that the putty compound in a suitable amount in granular or
EMI1.1
Porcelain. The improvement that occurs can be roughly assessed by calculation.
The known putties all have a higher coefficient of thermal expansion than porcelain. First
Line comes into consideration cement, whose cubic coefficient of thermal expansion is: a == 4-2. 10 while for porcelain a = o't). ioS can be adopted. A substance with lesser

EMI1.3
The coefficient of thermal expansion has the same value for this mixture as for porcelain. Explosive effects are completely excluded in this case when the cemented parts are heated. It is not necessary that the thermal expansions match exactly; In practice, one can be content with sewing the thermal expansion of porcelain and set putty together in the manner indicated.
