Title: METHOD FOR PRODUCING ALUMINUM TITANATE CERAMIC BODY
Abstract:
Disclosed is a method for producing an aluminum titanate ceramic body using a regenerated unfired starting material that is recovered during the production process of the aluminum titanate ceramic body. In this production method, a regenerated clay can be easily prepared and an aluminum titanate ceramic body having excellent mechanical strength and excellent thermal characteristics such as heat resistance and low thermal expansion can be obtained. Specifically disclosed is a method for producing an aluminum titanate ceramic body using a regenerated unfired starting material that is recovered during the production process of the aluminum titanate ceramic body, said method comprising: a step wherein a ground material having a diameter of 1 mm or less is obtained from the regenerated unfired starting material; a step wherein a regenerated clay containing the ground material and water is prepared; a step wherein a molded body is obtained by molding the regenerated clay; and a step wherein the molded body is fired.
