METHOD OF PRODUCING A MOLDED ARTICLE AND SLURRY FOR MOLDING

摘要

The inner shape of the body part in a hollow ceramic molded article constituting a precursor of a discharge vessel is precisely controlled so as to make a large improvement in the function of a discharge vessel formed by baking the hollow ceramic molded article. With the use of a core for molding having a wax molded article or molded article made of waxy substance, a slurry for molding is injected into a forming mold and cured, whereby a hollow ceramic molded article with a controlled inner shape of the body part is formed on the outer circumferential surface of the wax molded article or molded article made of waxy substance. The hollow ceramic molded article is baked to produce a discharge vessel.
