Synthesis and Characterization of Silicon Substituted Hydroxyapatite
ABSTRACT
A silicon-substituted hydroxyapatite was prepared using tetraethylorthosilicate as a silicon source to obtain a biomaterial having an improved biocompatibility. From the XRD analysis, it was confirmed that a single-phase hydroxyapatite containing silicon was formed without revealing the presence of extra phases related to silicon oxide or other calcium phosphate species. Silicon content was up to 3.32% by weight. Through $^$29/Si MAS NMR investigation we could confirm the presence of tetrahedral silicate in the framework of hydroxyapatite structure. Substitution of silicon into the hydroxyapatite framework (Ca$_$10/(PO$_4$)$_$6-x/(SiO$_4$)$_$x/(OH)$_$2-x/ reduced the amount of hydroxyl group to compensate for the extra negative charge of the silicate group, which is confirmed by FT-IR.
Key words: Hydroxyapatite, Silicon, Substitution, Bone, Biocompatibility
