Molded body, and method for producing the molded body

A molded body comprising:

• a first molded part formed by molding a first material slurry which contains a first material powder, a dispersant, and a gelling agent, and by causing the molded first material slurry to set;
• a second molded part bonded to the first molded part and formed by molding a second material slurry which contains a second material powder different in material from the first material powder, a dispersant, and a gelling agent, and by causing the molded second material slurry to set;
• and
• a third molded part bonded to one or both of the first and second molded parts and formed by molding a third material slurry which contains a third material powder different in material from the first and second material powders, a dispersant, and a gelling agent, and by causing the molded third material slurry to set.

A method for producing a molded body, comprising:

• forming a first mold cavity by placing a second mold on a planar surface or a curved surface of a first mold having the planar surface or the curved surface;
• forming a first molded part on the planar surface or the curved surface of the first mold by filling the first mold cavity with a first material slurry which contains a first material powder, a dispersant, and a gelling agent, so as to mold the first material slurry, and by causing the molded first material slurry to set;
• forming a second mold cavity by placing a third mold on the planar surface or the curved surface of the first mold from which the second mold is removed and on which the first molded part is formed;
• and
• forming a second molded part on the planar surface or the curved surface of the first mold by filling the second mold cavity with a second material slurry which contains a second material powder different in material from the first material powder, a dispersant, and a gelling agent, so as to mold the second material slurry in such a manner that the second material slurry comes into contact with the first molded part, and by causing the molded second material slurry to set;
• the method yielding the molded body in which the first molded part and the second molded part are bonded together and which has a planar surface or a curved surface having a region where the first molded part is exposed, and a region where the second molded part is exposed.

• forming a third mold cavity by removing a portion of the third mold corresponding to a side surface of the first mold different from the planar surface or the curved surface of the first mold on which the first and second molded parts are formed, and placing a fourth mold on the side surface;
• and
• forming a third molded part by injecting into the third mold cavity a third material slurry which contains a third material powder different in material from the first and second material powders, a dispersant, and a gelling agent, so as to mold the third material slurry in such a manner that the third material slurry comes into contact with one or both of the first and second molded parts, and by causing the molded third material slurry to set;
• the method yielding the molded body in which the first molded part and the second molded part are bonded together;
• which has a planar surface or a curved surface having a region where the first molded part is exposed, and a region where the second molded part is exposed;
• and in which the third molded part is bonded to a side surface of a bonded body consisting of the first and second molded parts, the side surface being different from the planar surface or the curved surface.
