Evolution of the Shell Structure of Hollow Submicrometer SiO2 Particles during Heat Treatment

Hollow submicrometer-sized SiO 2 particles are synthesized, and changes in the structure and morphology of their shells during heat treatment are studied. The dependences of the shrinkage of silica shells on the temperature of annealing of particles are studied. It is found the shells of hollow part...

Zusammenfassung:Hollow submicrometer-sized SiO 2 particles are synthesized, and changes in the structure and morphology of their shells during heat treatment are studied. The dependences of the shrinkage of silica shells on the temperature of annealing of particles are studied. It is found the shells of hollow particles are pore-free and impervious to liquids after annealing at 600°C.
