Abstract
Hydroxyapatite precipitation process involves the formation in the first phase of a solid-phase with amorphous structure (amorphous calcium phosphate), which in time turns into hydroxyapatite. Polynomial spline interpolation is a numerical method useful in mathematical modeling of this phase transformation process. By this method, experimental data are interpolated to obtain cubic spline polynomial function which can approximate reasonably well the experimental values of the degree of conversion at any pH between 8.5 ÷ 12. A very good agreement between the experimental and numerical results confirms the validity of the numerical procedure.
