Description

Die Erfindung bezieht sich auf ein Verfahren zum Herstellen von Formteilen, welche vorwiegend Cordierit- und/oder Anorthit- und/oder Spinell- und/oder Porsterit enthalten nach dem Hauptpatent The invention relates to a method for the production of molded parts, which predominantly cordierite and / or anorthite and / or contain spinel and / or porsterite according to the main patent

In dem Hauptpatent ist ein Verfahren vorgeschlagen worden, um vorwiegend Cordierit- und/oder Anorthit- und/oder Spinell- und/oder Porsterit-haltige Formteile herzustellen, mit dem Kennzeichen, dass einem hochtonerdehaltigen Silikatglaspulver Magnesiumoxyd zugesetzt wird.In the main patent, a method has been proposed to predominantly cordierite and / or anorthite and / or spinel and / or to produce molded parts containing porsterite, with the indicator that a high-alumina silicate glass powder Magnesium oxide is added.

Es wurde nun gefunden., dass-hochtonerdehaltiges Silikatglaspulver mit folgender Zusammensetzung besonders geeignet ist, um die erstrebten physikalischen und chemischen Eigenschaften der Formteile zu erhalten.It has now been found that silicate glass powder with high alumina content with the following composition is particularly suitable to achieve the desired physical and chemical properties of the molded parts.
