一种空心球状纳米羟基磷灰石颗粒及其制备方法。
The present invention is one kind of nanometer hollow spherical granular hydroxyapatite and its preparation process.
羟基磷灰石颗粒组新生骨组织完全成熟，羟基磷灰石颗粒仍大量存在，颗粒无明显吸收。
In ha group, the regenerated osseous tissue was matured completely, but there was still a large amount of ha granules left and the granules had not been absorbed obviously.
结果表明，溶胶-凝胶法合成出的羟基磷灰石颗粒细小均匀、比表面积大、活性高，具有很好的吸附性能。
The results indicate the sol-gel prepared HAP has the better adsorbed property for its small and uniform particle size, high specific surface area and activity.
