摘要:
采用固相法合成一系列氯羟磷灰石固溶体，通过XRD表征手段进行晶体化学分析，结果发现：随着Cl-含量增加，晶胞参数a增大，c减小.且二者呈线性关系：a=0.149 4 x+9.433 6，c=-0.062 8 x+6.902 6，符合Vegard定律.由Vegard定律计算的晶胞参数，与实测值比较发现，a与Cl-含量更符合理论关系，而c相差较大，说明通道离子的半径、位置和电负性对晶胞参数a影响较小、c影响较大.
Abstract:
A series of chlorhydroxyapatite solid solutions were synthesized by solidphase reaction method and investigated by XRD. The results indicated that unitcell parameters a value increases, c value decreases when Cl- contents increase gradually. Both have linear relation with Cl- contents: a=0.149 4 x+9.433 6，c=-0.062 8 x+6.902 6.This result accords with Vegard law. The unitcell parameter, which was calculated in the light of Vegard law, was comparable with the actual result. It is found that the relationship between a value and Cl- contents is much more coincident than that of c value through comparison with the theory result. It reveals that the radius， location and electronegativity of channelions can affect unitcell parameter c much more evidently than a value.
