| titleOfInvention | A kind of controllable object phase strontium-doped calcium phosphate powder and preparation method |
| abstract | The invention belongs to biomedical material technologies, disclose a kind of controllable object phase strontium-doped calcium phosphate powder and preparation method.The preparation method is：According to the molar ratio of (Ca+Sr)/P=1.67, by (NH 4 ) 3 PO 4 ·3H 2 O solution is added drop-wise to Ca (NO 3 ) 2 ·4H 2 O and (NH 4 ) 3 PO 4 ·3H 2 It is reacted in the mixed solution of O, product obtains strontium-doped calcium phosphate presoma powder through centrifuge washing, drying after grinding；Then by strontium-doped calcium phosphate presoma powder at a temperature of 900~1200 DEG C heat preservation sintering, controllable object phase strontium-doped calcium phosphate powder is obtained after cooling.The present invention is capable of the strontium-doped calcium phosphate two-phase powder of controllable preparation difference HA and β TCP ratios by adjusting strontium doping amount, has better bioactivity and application prospect compared with traditional calcium phosphate powder. |
