Abstract

The formation thermodynamics conditions of Si-substituted hydroxyapatite (Si-HA) from silicon-containing supersaturated calcium phosphate solutions (SSCPS) have been analyzed by the calculation of the supersaturations for various phases potentially precipitated at room temperature. The results have showed that the HA has the largest supersaturation and the silicon has no thermodynamic potential to precipitate in the form of CaSiO₃ from SSCPS when the pH value is less than 8, which suggests that the SSCPS can provide thermodynamic priority for the biomimetic formation of Si-HA coating on titanium substrate. By experiment, the biomimetic Si-HA coatings with different Si contents (0.14at% to 1.14at%) on titanium are produced by immersing in SSCPS, which confirmed the thermodynamic analysis results. In addition, the pH value in SSCPS during the deposition process are tailed.
