1氟-羟磷灰石的~1H NMR谱学研究显示文摘羟磷灰石(HAP)是重要的生物陶瓷材料,F的进入会影响其性质。通过对合成氟-羟磷灰石1H的NMR实验研究,发现HAP中结构羟基的1H化学位移与吸附水中的1H化学位移不同。在纯HAP中的1H的δ=-0.04×10-6,而随着F含量的增加,该谱峰不但变弱并消失,而且向低场区位移。在F相对含量为75%的F—HAP中,δ=0.44×10-6。随着F的替换,NMR谱中出现一个位于0.90×10-6~1.61×10-6的新谱蜂,其强度与F含量正相关,其位置也随着F的增加向低场区位移。这说明F的进入形成了氟氢键,从而产生了新的谱峰。由于这两个谱峰的位置和相对强度比均与F含量呈正相关,因此可以根据NMR谱中1H核的化学位移值及谱峰的相对强度来区分结晶态HAP与非晶态的磷酸盐,并对氟羟二元磷灰石的氟-羟基相对含量进行估算。刘羽 STOPPA F TONUCCI L 彭明生 2002硅酸盐学报2002,30,z1:4
