METHOD FOR SLUDGE CAST MOLDING FOR CERAMICS MOLDED BODY

摘要

PROBLEM TO BE SOLVED: To provide a method for sludge cast molding for a ceramics molded body capable of making a manufacturing cost low while when the ceramics molded body has a hollow part, increase or decrease of a wall thickness at a required position can be surely carried out. SOLUTION: When the ceramics molded body 7 has a hollow part 7a, as a slurry 6 a slurry made by dispersing ceramics source powder in water in an electrostatic charged state is used. A first electrode 4 provided to a casting mold 1 to be positioned at a first required outside of the hollow part 7, and a second electrode 5 provided to the casting mold 1 to be positioned at a second required outside of the hollow part 7a are used. Then a voltage is impressed between the first electrode 4 and the second electrode 5 under a state wherein the slurry 6 is filled in a cavity.
