Hollow silica particles, inorganic fillers, slurries, and resin compositions containing hollow silica particles, and methods for manufacturing hollow silica particle materials.

Abstract

A hollow silicon dioxide particle has one or more shells composed mainly of silicon dioxide inside the particle, which isolate the particle from the outside. When the hollow silicon dioxide particle is heated from 200°C to 550°C, the first amount of water removed from the hollow silicon dioxide particle is set as A [ppm]. When heated from 550°C to 900°C, the second amount of water removed from the hollow silicon dioxide particle is set as B [ppm]. Between the first amount of water removed and the second amount of water removed, 0.5 < (A / B) < 2.2 is satisfied.
