| titleOfInvention | Porous Nano-hydroxyapatite Microsphere with High Porosity and a Preparation Method Thereof |
| abstract | The invention provides a porous nano-hydroxyapatite microsphere with high porosity and a preparation method thereof. The size distribution of hydroxyapatite composite microspheres 5 prepared with the method is uniform, the particle size distribution range is 10-100 um; and the center particle size is 20-60um. Organic phases are added in a mixing process so that the suspension stability of suspension liquid can be improved effectively; the size distribution of the prepared microspheres is uniform, and the particle size is larger than the size of microspheres prepared with a traditional spray drying method; the microspheres can be used as internal support materials of 10 injections; the microspheres are better in sphere and high in porosity so that the inj ectable property of the materials is improved |
