Abstract
Hollow SiO2 particles of submicron size were synthesized and changes in the structures and morphology of their shells during heat treatment were investigated. The dependences of the shrinkage of silica shells on the annealing temperature of the particles were studied. It has been found that after annealing at 600°C, shells of hollow particles become non-porous and impermeable to liquid media.
