  • Process for the manufacture of thin plates with low binding strength
    Patent number: 4952343
    Abstract: Very thin plates of ceramic material with low binding strength are difficult to manufacture, since the stability of the moldings is very low, so that they can hardly be fed to a subsequent treatment stage after shaping. Therefore, after the ceramic material is molded into plate-shaped moldings, these moldings are pushed onto a flat carrier in the plane of their plate surface and are heated on it for a few minutes, so that iron sulfates form, which impart dimensional stability to the moldings.
