Sol-gel calcium phosphate ceramic coatings and method of making same |
摘要 |
This invention relates to novel sol-gel calcium phosphate, in particular hydroxyapatite ceramic coatings and processes of making same at low temperature. Such coatings are useful, inter alia, for dental implants and bone-metal contact appliances. A sol-gel process for preparing a crystallized hydroxyapatite which comprises: (a) hydrolysing a phosphor precursor in a water based medium; (b) adding a calcium salt precursor to the medium after the phosphite has been hydrolysed to obtain a hydroxyapatite gel; and (c) calcining the crystallized hydroxyapatite at a suitable elevated temperature. |
