Outline of Final Research Achievements

The optimum composition of the reactant solution in a process for producing calcium phosphates (CaP) on a titanium plate was studied based on a simulated body fluid (SBF). In particular, the effect of magnesium ion concentration was investigated, and consequently a condition under which CaP can be produced within a duration shorter than using SBF was found. Coexisting species for controlling the morphology was investigated. The effect of ordered alterations in height of the effective space of a small reactor on the flow of SBF was discussed. Microcapsules to compensate the decrease in calcium ions which have been deposited as CaP were prepared by dispersion polymerization, and their releasing property was characterized.
