The structure of dried and calcined bones from chicken, bovine, deer, pig, sheep and chamois was examined using X-ray Absorption Near Edge Structure (XANES) spectroscopy. The oxygen K-edge absorption edge indicates that the surface of dried bone has a larger proportion of carbonate than the interior that is made up of phosphates. The phosphorus L and K edge clearly indicate that pyrophosphates, α-tricalcium phosphate (α-TCP) and hydrogen phosphates of Ca do not exist in either the dried bone or calcined bone and phosphorus exists as either β-tricalcium phosphate (β-TCP) or hydroxyapatite, both in the dried and calcined conditions. The Ca K-edge analysis indicates that β-TCP is the likely form of phosphate in both the dried and calcined conditions.
采用 X 射线吸收近边结构（XANES）光谱法研究了鸡、牛、鹿、猪、羊和岩羚羊的干骨和煅烧骨的结构。氧 K 边吸收边表明，干骨的表面比由磷酸盐组成的内部具有更大比例的碳酸盐。磷 L 和 K 边清楚地表明，焦磷酸盐、α-磷酸三钙（α-TCP）和 Ca 的磷酸氢盐既不存在于干骨中也不存在于煅烧骨中，而磷则以β-磷酸三钙（β-TCP）或羟基磷灰石的形式存在，无论是在干燥还是煅烧条件下。Ca K 边分析表明，β-TCP 是干燥和煅烧条件下磷酸盐的可能形式。
