【 摘 要 】
The crystallization of hydroxyapatite (HA) in aqueous solution can be described by the mechanism ACP ® OCP ® HA. In this work, it was studied the influence of K+, Mg2+, SO42- and CO32- ions in the formation of ACP and in its conversion to OCP, using biomimetic coatings on metallic substrates of commercially pure titanium (Ti c.p.). The results showed that Mg2+ and CO32- ions favored both the formation of ACP and its conversion to OCP. Differently, K+ and SO42- ions did not influence the formation of ACP and, consequently, interfered in the conversion to OCP.
