Description

Verfahren zur Herstellung keramischer Trockenpreßmassen Zusatz zum Patent 68o 2o5 In denn Hauptpatent 68o 2o5 ist die Verwendung von Serizit allein oder in Mischung mit Talk als keramische Trockenpreßmasse. zur Herstellung von dicht gebrannten Gegenständen beschrieben worden. Es wurde nun gefunden, daß es vorteilhaft isst, solchen Serizitmassen auch Quarz zuzusetzen. Die Menge dieses Zusatzes kann zwischen 5 und 5o% betragen. Der Quarz bleibt, wenn er in größerer Menge beigemischt wird, zu einem Teil ungelöst und gibt so dem Scherben einen porzellanähnlichen Charakter. Es hat sich auch gezeigt, daß durch Zugabe von Quarz die mechanische Festigkeit der gebrannten Serizitmasse erhöht wird. Die Erfindung bringt weiter den Vorteil mit sich, daß die Aufbereitung des natürlich vorkommenden Serizitgesteins erübrigt wird. Ein Serizit, dem also fein verteilter Quarz beigemengt ist, kann der keramischen Verarbeitung unmittelbar zugeführt werden. Zur Erniedrigung der Sinterungstemperatur kann auch Feldspat in Menge von etwa 2 bis. I o % zugesetzt werden.Process for the production of ceramic dry molding compounds Patent 68o 2o5 In the main patent 68o 2o5 is the use of Serizite alone or mixed with talc as a ceramic dry molding compound. for making tight burned objects have been described. It has now been found to be advantageous eats to add quartz to such sericite masses. The amount of this addition can be between 5 and 5o%. The quartz remains when it is added in large quantities is, to a part, undissolved, giving the body a porcelain-like character. It has also been shown that the mechanical strength is increased by adding quartz the fired sericite mass is increased. The invention also has the advantage with it that the processing of the naturally occurring sericite rock is unnecessary will. A sericite, to which finely divided quartz is added, can be the ceramic Processing can be supplied immediately. To lower the sintering temperature can also contain feldspar in quantities of about 2 to. I o% are added.
