Powder for ceramic shaping, method of manufacturing ceramic shaped object, ceramic shaped object, and device

A powder for ceramic shaping to be used in an additive manufacturing method involving performing shaping through irradiation with laser light, the powder for ceramic shaping comprising oxide particles,

• wherein the oxide particles each contain a plurality of elements including at least Zr, Y, Si, and optionally Al, and contain at least silicon monoxide particles, and
• wherein when a content of the Zr is converted into a mass of ZrO2, a content of the Y is converted into a mass of Y2O3, a content of the Si is converted into a mass of SiO2, and a content of the Al is converted into a mass of Al2O3, the mass of ZrO2, the mass of Y2O3, and the mass of SiO2 with respect to a total amount of the mass of ZrO2, the mass of Y2O3, the mass of SiO2, and the mass of Al2O3 are represented by α (mass %), β (mass %), and γ (mass %), respectively, α, β, and γ satisfy expressions:
