采用单相共沉淀法和隋性气体保护下的固相反应法制备了不同通道离子替换固溶体磷灰石犤X1-X2AP犦。利用XRD对通道离子替换磷灰石固溶体进行了比较晶体化学研究,结果表明:晶胞参数随通道离子半径的增大,a0增大,c0反而减小,且OH-ClAP和F-OHAP变化呈线性关系,符合Vegard定律,而F-ClAP在富F-端的变化不呈线性关系;由于犤PO4犦四面体沿犤101犦方向的滑移,c0随a0的变化而变化,且c0-2与a0-2呈线性关系犤c0-2=-a0-2+3.2348犦。 A single-phase coprecipitation method and inert gas solid-phase reaction under the protection of different channel ion exchange solid solution apatite 犤 X1-X2AP 犦. XRD was used to compare the channel ion replacement of apatite solid solution. The results show that the unit cell parameters increase with the increase of channel ionic radius, a0 increases, c0 decreases, and OH-ClAP and F-OHAP changes Linear relationship with Vegard’s law, while the change of F-ClAP in F-rich is not linear; due to the slip of 犤 PO4 犦 tetrahedron in 犤 101 犦 direction, c0 changes with a0, and c0-2 and a0-2 has a linear relationship 犤 c0-2 = -a0-2 + ​​3.2348 犦.
