Title:
METHOD FOR PRODUCING CERAMIC FORMED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2004/035281
Kind Code:
A1
Abstract:
A method for producing a ceramic formed article which comprises forming a ceramic formed article by the use of the gel cast method, heating the resulting formed article to take out a solvent contained in the ceramic formed article to the exterior of the article, and then releasing the article from a mold. The solvent taken out from the article forms a solvent film between the outer surface of the article and the inner surface of the mold and the solvent film aids the release of the article from the mold. Thus, the above method can be used for preventing such a ceramic formed article from being damaged in a releasing operation.
