Ceramic green body and method for producing the same

A method for producing a ceramic green body comprising:

• a thin ceramic green sheet containing a ceramic powder, and a urethane resin that is produced by mixing isocyanate and polyol and serves as an organic binder;
• and
• a thin sheet-like molded body that is formed on the ceramic green sheet, and contains a ceramic powder and an organic binder not containing a hydroxyl group, the method comprising:
• mixing together a ceramic powder, an isocyanate, a polyol, and a solvent, to thereby prepare a ceramic slurry containing the ceramic powder, an unreacted portion of the isocyanate, an unreacted portion of the polyol, a urethane resin serving as an organic binder formed through reaction between the isocyanate and the polyol, and the solvent;
• molding the ceramic slurry into a thin sheet;
• further forming the urethane resin through reaction between the unreacted portion of the isocyanate and the unreacted portion of the polyol, the portions being contained in the molded body of the ceramic slurry, to thereby solidify the molded body of the ceramic slurry, and dry the molded body of the ceramic slurry to evaporate the solvent, so as to form the ceramic green sheet;
• mixing the ceramic powder, an organic binder not containing a hydroxyl group, and the solvent to form a paste;
• forming the produced thin sheet-like molded body of the paste on the produced ceramic green sheet;
• and
• drying the formed thin sheet-like molded body of the paste to evaporate the solvent, to thereby form the thin sheet-like molded body on the ceramic green sheet.
