Abstract
A method for estimating characteristics of a ceramic fired body, the method including: preparing a ceramic fired body by firing a formed green body; measuring a color of the ceramic fired body; and with use of a correlation between the color and at least one characteristic selected from a group consisting of a porosity, a pore diameter, and a thermal expansion coefficient previously determined for a ceramic fired body having a same composition as that of the ceramic fired body, estimating the at least one characteristic of the ceramic fired body from the color of the ceramic fired body, measured in the previous step.
