Abstract

Calcium titanate (CaTiO₃) films were prepared on commercially pure titanium (CP-Ti) by metal-organic chemical vapor deposition using Ca(dpm)₂ and Ti(O-i-Pr)₂(dpm)₂ precursors. The formation of hydroxyapatite (HAp, Ca₁₀)(PO₄) ₆(OH)₂) on CaTiO₃ film was investigated in a Hanks' solution. The formation rate of HAp was significantly affected by deposition conditions of CaTiO₃ films, particularly substrate temperature (T_sub). The time for the HAp formation was 3.6 Ms (42d) on the CaTiO₃ film prepared at T_sub = 873K, wheras that was 1.2 (14d) and 0.3 Ms (3 d) on that prepared at T_sub = 973 and 1073 K, respectively. Octacalcium phosphate (OCP, Ca₈H ₂(PO₄)₆·5H₂O) was identified on the CaTiO₃ film prepared at T_sub = 1073 K by the immersion for 21.6ks.
