ABSTRACT:
Shaped ceramic articles can be obtained by forcing a ceramic precursor gel into a belt provided with apertures corresponding to the shapes of the desired articles, freezing the gel in the apertures so that they can be removed without losing structural integrity and then removing the frozen articles from the belt and drying and firing them to produce the desired shaped ceramic articles.
