“…[9] The versatility of calcium titanate extends to its suitability as a material for the immobilization of radioactive waste [10] and a biocompatible coating for medical Ti implants. [11] The mixed oxide-ion and electronic conductivity of CaTiO 3 can be exploited in dense ceramic membranes for controlled oxygen separation as a means of producing pure oxygen or for integrating with catalytic oxidation, as described in recent reviews. [12] An important potential application is the partial oxidation of methane to syngas (a mixture of CO and H 2 ).…”

Mixed oxide‐ion and electronic conductivity can be exploited in dense ceramic membranes for controlled oxygen separation as a means of producing pure oxygen or integrating with catalytic oxidation. Atomistic simulation has been used to probe the energetics of defects, dopant‐vacancy association, nanoscale cluster formation, and oxide‐ion transport in mixed‐conducting CaTiO3. The most favorable energetics for trivalent dopant substitution on the Ti site are found for Mn3+ and Sc3+. Dopant‐vacancy association is predicted for pair clusters and neutral trimers. Low binding energies are found for Sc3+ in accordance with the high oxide‐ion conductivity of Sc‐doped CaTiO3. The preferred location for Fe4+ is in a hexacoordinated site, which supports experimental evidence that Fe4+ promotes the termination of defect chains and increases disorder. A higher oxide‐ion migration energy for a vacancy mechanism is predicted along a pathway adjacent to an Fe3+ ion rather than Fe4+ and Ti4+, consistent with the higher observed activation energies for ionic transport in reduced CaTi(Fe)O3–δ.

“…9) Manso et al prepared CaTiO 3 film in 4 mm thicknesses by sol-gel spincoating process and confirmed that morphological and structural suitability of CaTiO 3 coatings for their use as buffer layers between a TiAlV alloy and a HAp is strongly reinforced by the behavior of the CaTiO 3 surface in pseudo body fluid. 10) However, no studies on the HAp formation on CVD CaTiO 3 films were reported.…”

Calcium titanate (CaTiO 3 ) 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, Ca 10 (PO 4 ) 6 (OH) 2 ) on CaTiO 3 film was investigated in a Hanks' solution. The formation rate of HAp was significantly affected by deposition conditions of CaTiO 3 films, particularly substrate temperature (T sub ). The time for the HAp formation was 3.6 Ms (42 d) on the CaTiO 3 film prepared at T sub ¼ 873 K, wheras that was 1.2 (14 d) and 0.3 Ms (3 d) on that prepared at T sub ¼ 973 and 1073 K, respectively. Octacalcium phosphate (OCP, Ca 8 H 2 (PO 4 ) 6 Á5H 2 O) was identified on the CaTiO 3 film prepared at T sub ¼ 1073 K by the immersion for 21.6 ks.
