Abstract:
1. A process for producing an aluminum titanate-based ceramics body using a fired ceramics body recovered in a production process for an aluminum titanate-based ceramics body, comprising the following steps: (i) a step of preparing a pulverized product having a median particle diameter of 100 μm or less from the fired ceramics body; (ii) a step of preparing a regenerated clay containing the pulverized product and water; (iii) a step of shaping the regenerated clay to form a shaped body; and (iv) a step of firing the shaped body, wherein the particle diameter distribution of the pulverized product measured through laser diffractometry satisfies the following formula (1): (wherein D90 is a particle diameter corresponding to a cumulative percentage of 90% on a volume basis, and D10 is a particle diameter corresponding to a cumulative percentage of 10% on a volume basis).
