CHARACTERIZATION OF OXYHYDROXYAPATITES BY 31P SOLID-STATE NUCLEAR MAGNETIC RESONANCE

Oxyhydroxyaptites of chemical formulae Ca10(PO4)6(OH)0.30O0.85_??_0.85and Ca10(PO4)6(OH)0.70O0.65_??_0.65 where _??_ is an OH- ion vacancy are studied by 31P solid-state NMR. The obtained results, compared to those of ceramized hydroxyapatite, shows a great difference in the crystallographical struc...

Zusammenfassung:Oxyhydroxyaptites of chemical formulae Ca10(PO4)6(OH)0.30O0.85_??_0.85and Ca10(PO4)6(OH)0.70O0.65_??_0.65 where _??_ is an OH- ion vacancy are studied by 31P solid-state NMR. The obtained results, compared to those of ceramized hydroxyapatite, shows a great difference in the crystallographical structure of the two composed.
