Description

Verfahren zur Herstellung von keramischen lassen. Die Verwendung des Birnstufts zur Herstellung keramischer Massen, Glasuren und Gläser ist bereits früher vorgeschlagen worden. Die praktische Ausführung dieses Gedankens scheiterte jedoch daran, daß die Glasuren wegen der Ungleichmäßigkeit ihrer Farbe, die Massen durch Schlierenbildungen nicht den zu stellenden Anforderungen entsprachen.Process for the manufacture of ceramic leave. Using the Birnstufts for the production of ceramic bodies, glazes and glasses is already earlier has been proposed. However, the practical implementation of this idea failed Remember that the glazes, because of the unevenness of their color, penetrate the masses Formation of streaks did not meet the requirements.

Es wurde nun gefunden, daß der Bimstuff sich sehr gut für keramische Zwecke verwenden läßt, \venn man ihn vorher von den dem Tuff beigemengten Teilchen des Nebengesteins (Schülferchen) befreit hat, d. b. denjenigen Teilchen der Gestaltsmassen,welche den magmatischen Schmelzfluß vor der Eruption überdeckten und beim Ausbruch in fein verteilter Form von den vulkanischen Massen mitgerissen wurden.It has now been found that the pumice stuff works very well for ceramic Purposes, provided that it is previously removed from the particles admixed with the tuff has freed the neighboring rock (pupil), d. b. those particles of the shape masses which covered the magmatic melt flow before the eruption and in fine when it erupted dispersed form were carried away by the volcanic masses.

Die Entfernung dieser Nebenbestandteile kann in der verschiedenartigsten Weise erfolgen. Man kann hierzu beispielsweise die üblichen mechanischen Aufbereitungsmethoden, wie z. B. Schlämmen und Waschen, u. a. auch die sogenannte Zentrifugalscheidung, anwenden. Auch kann unter Umständen die magnetische Aufbereitung in Betracht kommen, mit deren Hilfe die Eisenerzteilchen entfernt werden. Schließlich sei in diesem Zusammenlang auch noch die elektrische Aufbereitung erwähnt.The removal of these secondary constituents can be carried out in the most varied of ways Way. For example, you can use the usual mechanical processing methods, such as B. sludging and washing, i.a. also the so-called centrifugal separation, use. Under certain circumstances, magnetic processing can also be considered, with the help of which the iron ore particles are removed. Finally be in this Also mentioned together with the electrical processing.

Abgesehen von den vorstehend genannten Aufbereitungsmethoden kommt für die Entfernung der störenden Beimengungen bzw. Nebenbestandteile auch die chemische Behandlung des Bimstuffs in Betracht, indem beispielsweise mittels Säuren diese Bestandteile herausgelöst werden.Apart from the above-mentioned treatment methods comes for the removal of the disturbing admixtures or secondary components also the chemical one Treatment of the pumice into consideration, for example by means of acids Components are extracted.

Je nach den vorliegenden Verhältnissen lassen sich natürlich auch die oben angegebenen `-erfahren vereinigen.Of course, depending on the prevailing conditions unite the above-mentioned `-experiences.

Durch die vorliegende Erfindung ist dem Bimstuff ein vollkommen neues Anwendungsgebiet erschlossen worden.With the present invention the pumice stuff is a completely new one Application area has been opened up.
