Approach: Sol gel route was used to prepare yttria stabilized zirconia. Then it was hydroxylated with 5M H3PO4 for formation of Zr-OH group. Moreover, the growth rate of calcium and phosphate on zirconia substrate was examined using simulated body fluid. Results: From x-ray diffraction pattern, confirmed the phase formation of tetragonal zirconia. SEM analysis shows the growth of Ca-P on zirconia in SBF solution. AFM represents the particle size of Ca-P is about 68-70 nm for 7 days SBF and exactly 60 nm for 15 days SBF solution. Conclusion: The results showed that the yttria stabilized zirconia in SBF solution through hydroxylation gives better results.}, journal = {American Journal of Applied Sciences}, publisher = {Science Publications} }
