“…However, there is a questionable opinion that ACPs might have an apatitic structure but with a crystal size so small, that they are X-ray amorphous. This is supported by X-ray absorption spectroscopic data (EXAFS) on biogenic and synthetic samples (Harries et al 1986(Harries et al , 1987Taylor et al 1998;Peters et al 2000). On the other hand, it was proposed that the basic structural unit of the precipitated ACPs is a 9.5 Å diameter, roughly spherical cluster of ions with the composition of Ca 9 (PO 4 ) 6 (Fig.…”

“…The X ray diffraction data of as-dried powder (Figure 1) shows its poor crystallinity. Its diffractogram closely resembles that of bone 12,13 . The infrared spectra (Figure 2) ) which exists in non-stiochiometric hydroxyapatite (HAP) 14 .…”

“…Antropología física, medicina, etc.). Por un lado, podemos decir que el hueso es un composite (7), es decir, un biomaterial que presenta una fase orgánica y una fase inorgánica, y que juntas constituyen una estructura altamente jerarquizada (8). La fase orgánica está compuesta por diversas proteínas tales como colágeno tipo I, osteocalcina, osteonectina u osteopontina (9); mientras que la hidroxiapatita (Ca 10 (PO 4 ) 6 (OH) 2 ) y en menor medida el fosfato de calcio (Ca 3 (PO 4 ) 2 ), además de otros elementos minoritarios como magnesio (Mg 2+ ) o sodio (Na + ) constituyen la fase inorgánica (10).…”
