Characterization of Ion Substituted Calcium Phosphate Apatites Produced via Sol-Gel Method

Hydroxyapatite (HA) is one of the most popular biomaterial which has a wide variety of applications. Although HA biomaterials superior properties, dissolution behavior and implant stability properties of HA needs to be improved. One of the promising solution for these problems is incorporating Flourine (F) and Zinc (Zn) ions into HA structure. Sol-gel technique which has an effortless process control procedure, emerged as an ideal candidate for producing ion doped HA powders. Pure, F and Zn substituted HA powders obtained through sol-gel technique and SEM, EDX, XRD and FTIR analysis were performed. Results showed that F and Zn substitution into HA lattice was successful.
