研究了TEOS和CTAB对HAp晶体生长和HAp/SiO2杂化体形貌的影响。成功地实现了在HAp纳米颗粒上介孔二氧化硅的形成，并且SBET和RBJH值随着进料Ca/P比而改变。HAp/SiO2杂化材料具有较高的SBET值和中孔。结果表明，SiO2相与HAp的a面发生特异性相互作用，HAp沿轴向沿着方向发生相互作用，形成各向异性的杂化结构。
The additive effect of TEOS and CTAB on the HAp crystal growth and HAp/silica hybrid shape was investigated. The mesoporous silica formation on the HAp nanoparticles was successfully achieved, and theSBETandRBJHvalues were changed with the feed Ca/P ratio. The HAp/silica hybrids exhibited the higherSBETvalues with the mesopores. It was suggested that the silica phase specifically interacted with thea-plane of HAp and subsequently the HAp along with thec-axis direction to be anisotropic hybrid shapes.
