Abstract
A ceramic compact having a patterned conductor is obtained by coating the patterned conductor with a slurry and then by hardening the slurry. The slurry is prepared by mixing a thermosetting resin precursor, a ceramic powder, and a medium. In the ceramic compact, an isocyanate- or isothiocyanate-containing gelling agent and a hydroxyl-containing polymer are reacted and hardened to produce a thermosetting resin. The hydroxyl-containing polymer is preferably a butyral resin, an ethylcellulose-based resin, a polyethyleneglycol-based resin, or a polyether-based resin.
Claims2
A method for producing a ceramic compact, comprising:
- a conductor forming step of forming a patterned conductor;
- a slurry supplying step of coating said patterned conductor with a slurry prepared by mixing a thermosetting resin precursor, a ceramic powder, and a medium;
- a slurry hardening step of hardening said slurry,
- wherein said patterned conductor is formed on a film, in said conductor forming step,
- wherein said film having said patterned conductor is placed in a casting mold and said slurry is cast into said casting mold, in said slurry supplying step, and
- a removing the film step for removing the film after the slurry has hardened,
- wherein said film and another film are stacked with a spacer interposed therebetween in said casting mold such that said patterned conductor faces said another film, and said slurry is cast into a space formed by said spacer, in said slurry supplying step, and
- wherein the thermosetting resin precursor comprises hydroxyl-containing polymer and one of an isocyanate-containing gelling agent and an isothiocyanate-containing gelling agent.
