Carbonate- and Si-involving hydroxyapatite (C-HA, Si-HA) as well as hydroxyapatite (HAp) was prepared through wet chemical processes. Magic angle Spinning (MAS) NMR spectroscopy was applied together with Cross-Polarization (CP) techniques to study chemical environments around the guest oxo-anions. C-HA involved at least four carbonate sites, but the one for ∼168 ppm was left unassigned. In Si-HA, only Q0 (SiO44-) replaced the phosphate ion site but other Si atoms were polymerized and present on the surface or in the grain boundary of the Si-HA particles. The 31P MAS and CP-MAS spectra indicated the absence of HPO42- in the lattice, and suggested the presence of an amorphous phosphate phase on the particle surface.
