Abstract
The method of predicting a formed body density includes: a correlation calculating step of obtaining the correlation between the formed body density of the formed body and the porosity of the fired body; and a formed body density predicting step including: in a case of preparing a kneaded material A from a ceramic raw material having substantially the same composition as a ceramic raw material used for preparing a kneaded material, preparing a formed body B by forming the kneaded material A, preparing a dried body C by drying the formed body B, and preparing a fired body D having a desired porosity by firing the dried body C, calculating a predicted value of the formed body density of the formed body B corresponding to the desired porosity of the fired body D using the correlation.
