CERAMIC ARTICLE MANUFACTURING METHOD AND CERAMIC ARTICLE
To provide a silica-based ceramic structure that is high in model accuracy and is excellent in mechanical strength.SOLUTION: The ceramic article manufacturing method is characterized by having: (i) a step in which a powder containing an absorber that absorbs light of the wavelength contained in the irradiating laser beam and containing silicon dioxide as the main component; (ii) a step in which, by irradiating the powder with a laser beam, the powder is sintered or melted and solidified; and (iii) a step in which the modeled product formed by repeating the steps (i) and (ii) is heat-treated at 1470°C or higher and lower than 1730°C.SELECTED DRAWING: Figure 1
【課題】 造形精度が高く機械的強度に優れるシリカ系のセラミックス構造体を提供する。【解決手段】 （ｉ）照射するレーザービームに含まれる波長の光を吸収する吸収体を含み、二酸化ケイ素を主成分とする粉末を配置する工程と、（ｉｉ）前記粉末にレーザービームを照射することにより、前記粉末を焼結または溶融および固化させる工程と、（ｉｉｉ）前記工程（ｉ）と（ｉｉ）とを繰り返して形成した造形物を１４７０℃以上１７３０℃未満で加熱処理する工程と、を有することを特徴とする。【選択図】 図１
