Description
Keramische Masse aus Serizit Es ist bekannt, Serizit, der eine besondere Glimmerart ist, keramisch zu verarbeiten. Man hat bereits Serizit allein oder in einer Mischung mit Talk als Trockenpreßmasse zur Herstellung von dichtgebrannten Gegenständen verwendet.Ceramic mass from Serizit It is known that Serizit is a special one The type of mica is to be processed ceramically. One already has sericite alone or in a mixture with talc as a dry molding compound for the production of tightly burned Objects used.
Gemäß der vorliegenden Erfindung wird eine keramische Masse, die aus Serizit allein oder aus einer Mischung mit Talk oder anderen Stoffen besteht, durch den Zusatz von Tonerde verbessert. Die Tonerde kann beispielsweise in Mengen von 1o bis 30 °/a zugesetzt werden und bewirkt eine wesentliche Erhöhung der Festigkeit und Isolationswerte. Z. B. konnte durch Zusatz von 2o % Tonerde zu einer Serizitmasse die Festigkeit um 50 °/o gesteigert werden, so daß es möglich ist, die guten Festigkeiten der reinen Steatitmassen zu erreichen (rqoo kg/cm2). Gegenstände aus der erfindungsgemäßen Masse können für die verschiedensten Zwecke, insbesondere in der Elektrotechnik, vorteilhaft verwendet werden. Die Tonerde kann in calcinierter oder geschmolzener Form zugegeben werden. Im letzteren Fall ist für ausreichende Vermahlung Sorge zu tragen. Die Masse läßt sich im Trockenpreßverfahren leicht verarbeiten und gibt einen dichten homogenen Scherben. Die durch den Zusatz von Tonerde bedingte geringe Erhöhung der Brenntemperatur kann mit Rücksicht auf die erzielten Verbesserungen- der Festigkeits- und Isolationseigenschaften nicht als nachteilig angesehen werden, da sich die erfindungsgemäße Masse ohne weiteres in den vorhandenen bzw. gebräuchlichen Porzellanöfen brennen läßt.According to the present invention, a ceramic mass which consists of sericite alone or of a mixture with talc or other substances is improved by the addition of alumina. The alumina can be added, for example, in amounts of 10 to 30 ° / a and brings about a significant increase in strength and insulation values. For example, by adding 20 % clay to a sericite mass, the strength could be increased by 50%, so that it is possible to achieve the good strengths of the pure steatite masses (around kg / cm2). Objects made from the composition according to the invention can advantageously be used for a wide variety of purposes, in particular in electrical engineering. The clay can be added in calcined or molten form. In the latter case, sufficient grinding must be ensured. The mass can be easily processed in the dry pressing process and gives a dense, homogeneous body. The slight increase in the firing temperature caused by the addition of alumina cannot be regarded as disadvantageous in view of the improvements in strength and insulation properties achieved, since the composition according to the invention can easily be fired in existing or customary porcelain ovens.
