Ceramic article production method and ceramic article
Provided are a method of manufacturing a ceramic article including a porous portion in which improvement in mechanical strength of a modeled article is achieved while high modeling accuracy is obtained, and a ceramic article. The method of manufacturing a ceramic article includes the steps of: (i) irradiating powder of a metal oxide containing aluminum oxide as a main component with an energy beam based on modeling data to melt and solidify or sinter the powder, to thereby form a modeled article including a porous portion; (ii) causing the modeled article formed in the step (i) to absorb a liquid containing a zirconium component; and (iii) heating the modeled article that has absorbed the liquid containing the zirconium component, wherein, in the absorbing step, the liquid is absorbed so that a ratio of the zirconium component in a metal component contained in the porous portion becomes 0.3 to 2.0 mol %.
