Abstract

Zur Herstellung von großformatigen porösen grobkera­ mischen Formkörpern geringer Dichte wird eine tonminera­ lische Masse aus natürlich blähfähigen oder blähfähig gemachten Stoffen, wie Basalte, Perlite, Schiefer und Tonen mittels thermischer, chemischer und mechanischer Behandlung gleichmäßig gebläht. Es werden plattenförmige getrocknete und gegebenenfalls vorgewärmte dünne kompak­ te Tonmassen seitlich und nach unten geometrisch unnach­ giebig, nach oben gemäß dem Verlauf des Blähens geome­ trisch veränderlich nachgiebig formschlüssig aber nach allen Seiten gasdurchlässig durch Rollen abgestützt, sowie nach hinten durch die mittels Reibschluß gehaltene ungeblähte und nach vorn durch die mittels Reibschluß gehaltene fertig geblähte Tonmasse allseitig abgestützt, durch Wärmezufuhr von oben und unten zwischen den und über die Rollen und unter Zufuhr von oxidierenden Gasen an die Oberflächen der plattenförnigen Tonmassen solange erwärmt und gebläht, bis ein plattenförmiger Formkörper der gewünschten geringen Dichte gebildet ist. Erreicht werden auf diese Weise eine hohe Geschwindigkeit und Gleichmäßigkeit der Erwärmung beim Blähvorgang ohne Ansintern der blähenden Tonmasse an der Vorrichtung, eine hohe Formstabilität der Tonmasse während des Blähens bei geringem Kraftaufwand für die Formgebung und den Transport der blähenden Tonmasse und damit großformatige Formkörper mit gleichmäßig geringer Dichte sowie gleich­ mäßiger und hoher Porosität, Festigkeit und Formgenauig­ keit sowie eine wirtschaftliche Herstellbarkeit.
