| Abstract: |
| Hydroxyapatite(HA) powder was prepared by means of chemical precipitation & spray-drying method.Three types of HA powder with three different heat treatment processes were studied through TEM,SEM and XRD.The result shows that the HA powder with the heat treatment of flame refuse has the best crystallinity and more smooth and compact grain surface,thus improving the property of thermal spraying. |
