WIPO Patent Application WO/2020/250960
Kind Code:
A1
Abstract:
The method for producing an inorganic material (S10) of the present invention includes a vitrification step (S12) for vitrifying at least part of a mixed powder (MP) by using a ring-ball mill mechanism (70) to apply shear stress and compressive stress to a mixed powder (MP) obtained by mixing powders of multiple types of inorganic compounds and a dispersion step (S13) for dispersing the vitrified mixed powder (MP) after the vitrification step (S12), and a combination of the vitrification step (S12) and dispersion step (S13) is repeated multiple times to obtain a vitrified inorganic material powder from the mixed powder (MP).
