Abstract
Synthetic apatites differ in forms and compositions due to the different sintering method, and precipitation of nitrogenous species is often noted.In this study, we make further investigations on the precipitation of nitrogenous species in commercial synthetic apatite using diffuse reflectional spectrophotometry to determine IR absorptions for the analization of spectral difference, etc.
The result is that the absorption of nitrogenous species which is considered as CN22-, OCN- shown at 2,010 cm-1 and 2,200 cm-1 of all samples except CO3-Ap and the recognization of these IR absorption in synthetic apatites of different types suggests the neccesity of further detailed investigations on the biocompatibility of synthetic apatite.
