Tetragonal ZrO2 was coated on the SiO2 nanoparticles by liquid phase deposition. In this study, the liquid phase deposition was carried out using the boric acid as the fluoride ion scavengers. The amount of the nano-coated ZrO2 was controlled by the amount of the fluoride ion scavengers. As a result, the highest yield of the ZrO2 nanocoating process was attained at [HBO3]/[Zr] = 20.0 condition. After the annealing at 900°C for 1 hour, the tetragonal ZrO2 was confirmed by XRD and Raman analysis. Namely, the SiO2-ZrO2 core-shell hybrid particles was obtained by controlled liquid phase deposition process.
