GREEN FORMED BODY, AND PROCESS FOR PRODUCTION OF HONEYCOMB STRUCTURE

摘要

The present invention provides a green formed body in which the porosity of a honeycomb structure can be controlled easily. One embodiment of the present invention is a green formed body which comprises a honeycomb-like cylindrical body (70) in which multiple through-holes (70a) that are almost parallel to one another are formed, wherein the cylindrical body (70) comprises a ceramic raw material powder and a fluorine source and the ceramic raw material powder is burned to form an aluminum titanate ceramic and/or a cordierite ceramic.
