HOLLOW INORGANIC PARTICLE AND METHOD FOR PRODUCING SAID HOLLOW INORGANIC PARTICLE

摘要

Provided is a hollow inorganic particle that has excellent strength despite having high porosity.　Provided is a hollow inorganic particle in which the thickness of the thinnest part of an outer shell/the thickness of the thickest part of the outer shell is 0.80 or greater. The hollow inorganic particle according to this technology can be produced by a production method comprising: a coating step for coating core particles composed of organic polymers by using a silicone-based compound; and a core particle removal step for removing the core particles, wherein in the coating step, a dispersant adding step for adding a dispersant to a core particle dispersion and a surfactant adding step for adding a cationic surfactant after said dispersant adding step are carried out.
