Tetragonal ZrO 2 was coated on the SiO 2 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 nanocoated ZrO 2 was controlled by the amount of the fluoride ion scavengers. As a result, the highest yield of the ZrO 2 nanocoating process was attained at [HBO 3 ]/[Zr] = 20.0 condition. After the annealing at 900°C for 1 hour, the tetragonal ZrO 2 was confirmed by XRD and Raman analysis. Namely, the SiO 2 -ZrO 2 core-shell hybrid particles was obtained by controlled liquid phase deposition process.
