CERAMIC POWDER, METHOD OF MANUFACTURING CERAMIC POWDER, AND METHOD OF MANUFACTURING CERAMIC OBJECT USING THE CERAMIC POWDER
Ceramic powder to be used for additive manufacturing of a ceramic object by irradiating the powder with laser light includes a first group of particles of a first inorganic compound showing an average particle diameter of not less than 10 μm and not more than 100 μm and a second group of particles of a second inorganic compound having an absorption band at the wavelength of the laser light and showing an average particle diameter smaller than the average particle diameter of the first group of particles. Particles belonging to the second group of particles are arranged on the surfaces of particles belonging to the first group of particles. A high-precision ceramic object can be obtained in a short time by using the ceramic powder.
