Method for the preparation of carbonated hydroxyapatite compositions |
摘要 |
A method for the preparation of a carbonated hydroxyapatite composition which has a density of at least 95% of the theoretical density, which method comprises sintering at substantially atmosphere pressure a green carbonated hydroxyapatite composition containing up to 20% by weight of CO3<2><-> ions and having a green density of from 25 to 60% of the theoretical density at a temperature in the range of from 750 DEG to 1450 DEG C in carbon dioxide containing from 0.001 to 0.10 grams of water per litre of gas, the sintering temperature being selected within the above range and the green composition being sintered for a period of time sufficient to cause the green composition to densify to at least 95% of the theoretical density. |
