| Outline of Final Research Achievements |
A small reactor involving a confined space was fabricated, in which calcium phosphate (CaP) was produced on titanium by flowing a simulated body fluid (SBF). The mixing characteristics in the reactor were evaluated by the impulse response testing. The relationship between the intermittently flowing conditions of SBF and the CaP yield was discussed. The crystalline phase of the product was identified as calcium-deficient hydroxyapatite. It was found that dispersion intensity is useful as an evaluation index of mixing characteristics instead of dispersion number used in general. The production of CaP was accelerated at larger dispersion intensity more than static condition. The knowledge on the effects of the SBF composition was also obtained.
