| 摘 要： | 采用化学沉积技术在SiO2-A12O3空心微珠表面沉积羟基磷灰石获得SiO2-A12O3/HA空心微球.结果表明羟基磷灰石以颗粒状均匀地沉积在空心微珠表面,且所得微球仍具有理想的球形结构；SiO2-Al2O3/HA空心微球中除构成SiO2-A12O3空心微珠的主要组分(3Al2O3·2SiO2、SiO2)及羟基磷灰石外...

| Abstract: | SiO2-Al2O3/HA hollow microspheres are fabricated by chemical method through depositing hydroxyapatite particles on the surface of SiO2-Al2O3 hollow microspheres.The results indicated that both before and after being deposited,samples can own ideal spherical structure,and hydroxyapatite particles are coated on the surface of SiO2-Al2O3 hollow microspheres.In addition to 3Al2O3·2SiO2,SiO2 and hydroxyapatite,a few of Ca2SiO4 and Ca(OH)2 also exist in the products. |
