ABSTRACT
Bulk calcium phosphate biomaterials without sintering were synthesized at room temperature by infiltrating various orthophosphate aqueous solutions into a porous Ca(OH)2 green powder compact. These orthophosphate aqueous solutions were prepared from a different ratio of Ca(OH)2/H3PO4 up to pH=12. The infiltrated specimens did not show any shape or dimension changes at a lower concentration of H3PO4 or a liquid with pH>2. When the liquid contained some supersaturated solids or precipitates, the infiltrated specimens showed their reacted phases at the surface similar to these supersaturated precipitates, which were Ca(H2PO4)2鈭橦2O (MCPM), CaHPO4鈭�2贬2O (DCPD), or Ca10 (PO4)6 (OH)2 (HA) as pH was increasing. Under a liquid infiltration with a lower concentration of H3PO4 liquid, a functional graded calcium orthophosphate composite was observed. Furthermore, relationships among processing factors like pH plus impurities and liquid concentration, phase formation, and microstructure of infiltrated specimens were discussed in detail.
