Abstract:
According to the present invention, a ceramic article having good properties is obtained. A method for molding a ceramic material comprises: a step for mixing a ceramic powder, a sintering aid, a resin, a curing agent, and a solvent to prepare a ceramic casting liquid that becomes a ceramic material; a step for injecting the ceramic casting liquid into a mold which can be dissolved in a non-aqueous solvent and inside which a cavity is formed; a step for forming a cured body having a desired shape by curing the resin in the ceramic casting liquid that has been injected into the mold; and a step for dissolving the mold in a non-aqueous solvent to release the cured body. The mold is formed from a soluble resin which can be dissolved in a non-aqueous solvent, and has an elastic modulus of 500 [MPa] to 5,000 [MPa] and a thermal conductivity of 0.05 [W/mK] to 0.40 [W/mK].
