A kind of calcium deficiency type aluminium doped hydroxylapatite powder and its preparation method and application |
| abstract |
The present invention relates to a kind of calcium deficiency type aluminium doped hydroxylapatite powder and its preparation method and application, the composition general formula of the calcium deficiency type aluminium doped hydroxyapatite material is Ca 10‑1.5x Al x (PO 4 ) 6 (OH) 2 , wherein 0 x≤2 <, the surface of the calcium deficiency type aluminium doped hydroxyapatite material has calcium ion vacancy so that the surface is in elecrtonegativity.Preparation method of the present invention is easy to operate, and yield is larger.Used low raw-material cost is suitable for large-scale production, has prospects for commercial application and value.By-product of the invention only has water, and outer source ion in addition to aluminum will not be introduced in product hydroxy apatite structure, thus can eliminate the influence of foreign ion. |
