Hollow inorganic particle and method for producing said hollow inorganic particle

Abstract

Provided is a hollow inorganic particle having excellent strength despite having high porosity. Provided is a hollow inorganic particle including an outer shell, the thinnest part of the outer shell/the thickest part of the outer shell being 0.80 or more. The hollow inorganic particle according to the present technology can be produced by a production method including: a coating step of coating core particles made of an organic polymer with a silicone-based compound; and a core particle removal step of removing the core particles. The coating step includes: a dispersant addition step of adding a dispersant to a core particle dispersion; and, after the dispersant addition step, a surfactant addition step of adding a cationic surfactant.
