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 (Tsub). The time for the HAp formation was 3.6 Ms (42d) on the CaTiO3 film prepared at Tsub = 873K, wheras that was 1.2 (14d) and 0.3 Ms (3 d) on that prepared at Tsub = 973 and 1073 K, respectively. Octacalcium phosphate (OCP, Ca8H 2(PO4)6·5H2O) was identified on the CaTiO3 film prepared at Tsub = 1073 K by the immersion for 21.6ks.
