Abstract The graphite-silica (SiO2@GP) core-shell particles were formed via thermal chemical vapor deposition at 1100 °C. The synthesis’s growth times were varied at 1, 5, 10, 30, and 60 min. The properties of SiO2@GP particles with different growth times were systematically analyzed and investigated. At a growth time of 10 min, major SiO2 peaks and the principal of the graphene were observed. The SiO2 particles and thin GP sheets covering their surfaces are clearly observed.
