Variations in Atomic Disorder in Biogenic Carbonate Hydroxyapatite Using the Infrared Spectrum Grinding Curve Method

摘要: Biogenic carbonate hydroxyapatite crystals are inherently disordered at the atomic level due mainly to substitutions of various ions in crystal structure, and, case bone family materials, fact that these very small have a large surface-to-bulk ratio. Characterization extent disorder is much interest, as this relates stability and hence solubility crystals. Here infrared spectrometry grinding curve approach developed for calcite, adapted hydroxyapatites. The splitting factor plotted against full width half height strong phosphate absorption peak function increased sample. By doing so, contribution particle size shape peaks better separated from shape. It shown differences exist between dentine, cementum, which could reflect and/or defects within crystal. als systematic enamel samples different taxa, we assume only reflects method can be used characterize natural hydroxyapatites, well many types synthetic hydroxyapatites biomedical implants.
