Verfahren zur Herstellung poröser feuerfester Steine.

Kieselguhr und einem geeigneten Bindemittel, welches Material überall dort zu Isolierungszwecken Anwendung finden soll, wo Temperaturen in Betracht zu ziehen sind, welchen Kor) : odur Korkstein nicht mehr standhalten können.
Die Erfindung besteht in dem Zusatze von zerkleinertem Kork in verschiedenen Feinheitsgraden (Korkmehl oder Korkschrot, letzteres in Stückchen bis zu zirka 5 mm Durchmesser) oder in beiden genannten Formen gleichzeitig zu obgenannten Materialien und beruht auf der Ausnutzung der Elastizität des zerkleinerten Korkes in verschiedenen Feinheitsgradcn zur Herstellung einer plastischen

die Elastizität des zerkleinerten Korkes die Hauptrolle für das gute Gelingen des be- schriebenen Verfahrens und bezüglich der Eigenschaften des erhaltenen Produktes spielt.
Zur Erhöhung der Festigkeit kann man auch, wenn dies für gewisse Zwecke orforderlich sein sollte, geringe Mengen eines Flussmittels der ursprünglichen Mischung zusetzen.
Als zweckmässig hat sich folgendes Mischungsverhältnis ergeben :
15 Gewichtsteile Kieselguhr, 1 Gewichtsteil Ton und 15 Gewichtsteile zerkleinerter Kork. Diese Verhältniszahlen ändern sich selbstverständlich mit den Eigenschaften der Rohmaterialien. Diese werden mit Wasser zu einem formbaren Teig geknetet und die

Kieselguhr and a suitable binding agent, which material should be used for insulation purposes wherever temperatures have to be taken into account, which Kor): odur cork stone can no longer withstand.
The invention consists in the addition of crushed cork in different degrees of fineness (cork flour or cork grist, the latter in pieces up to about 5 mm in diameter) or in both forms mentioned at the same time to the above materials and is based on the utilization of the elasticity of the crushed cork in different degrees of fineness Making a plastic

Probably one has to generate cavities in ceramic masses and fired artificial stones, such as. B. in porcelain mass for the manufacture

It should also be noted that cork and cork grist are advantageously used to carry out the present method. But one also achieves very good results

EMI2.1
the elasticity of the crushed cork plays the main role for the success of the described process and with regard to the properties of the product obtained.
To increase the strength, you can, if this should be necessary for certain purposes, add small amounts of a flux to the original mixture.
The following mixing ratio has proven to be useful:
15 parts by weight of kieselguhr, 1 part by weight of clay and 15 parts by weight of crushed cork. These ratios of course change with the properties of the raw materials. These are kneaded with water to form a malleable dough and the

Annealed in a known manner until the organic parts are completely burned.
