Method for drying ceramic compact

Abstract

A method for drying a ceramic compact includes: maintaining a ceramic compact containing a gelable binder in a condition having a humidity of 70% or higher and having a temperature the same as or higher than a gelating temperature of the gelable binder for a predetermined period of time; and vaporizing water in the ceramic compact. According to the drying method, gelable binder gelates before water is vaporized in a compact, and thereby the compact hardly deforms in accordance with drying shrinkage. Further, the drying method gives uniform drying to the compact in comparison with the conventional hot-air drying. Therefore, use of the compact produced by the drying method significantly reduces deformation, which results from nonuniformity of drying, during the firing process, and a fired body having excellent preciseness in configuration is obtained.
