PROCESS FOR MAKING A CALCIUM PHOSPHATE-BASED BIOMEDICAL MATERIAL |
| 摘要 |
<p>Biomedical materials and, in particular, to substituted calcium phosphate (e.g. apatite and hydroxyapatite) materials for use as synthetic bone. A synthetic calcium phosphate comprising silicon and a trivalent cation having a formula Ca10−yMy(PO4)6−x(SiO4)x(OH)2−x+y where M is a trivalent cation, 0<x<1.3 and 0<y<1.3. The trivalent cation is one or more of yttrium, scandium, aluminium and the Lanthanide elements. Preferably, the trivalent cation is or comprises yttrium. The trivalent cation is believed to substitute for the calcium ion in the hydroxyapatite lattice.</p> |
