Abstract

The invention is to provide a process for producing an aluminum titanate-based ceramics body, wherein, as a regenerated starting material, a fired body recovered in a production process for an aluminum titanate-based ceramics body is used and the aluminum titanate-based ceramics body excellent in a mechanical strength and in a thermal characteristics such as low thermal expansion and heat resistance can be obtained. The invention provides 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: a step of preparing a pulverized product having a median particle diameter of 100 μm or less from the fired ceramics body; a step of preparing a regenerated clay containing the pulverized product and water; a step of shaping the regenerated clay to form a shaped body; and a step of firing the shaped body.
