摘要: Solid-state NMR studies on bone, bone mineral standards and collagen are reviewed. spectroscopy was mostly applied to the confirmed that structure resembles of calcium carbonatoapatite type B. Apatite in found be deficient structural hydroxyl groups. Concentration distribution hydrogenphosphate carbonate ions, water apatite crystals (interior vs surface crystal defects positions) were closely investigated. The characterization organic matrix still remains a challenge for future research.
