| Abstract |
| Ca-hydroxyapatite [Ca10(PO4)6(OH)2] powder was prepared by wet chemical route. The powder was calcined (900oC) and added with various amounts of pore former to produce 4 different mixes. All were pressed cold isostatically (150 MPa) and debinded to remove pore former from the structure. The fragile structures thus obtained were sintered (1250oC) and the pore size distributions of the porous solids were studied by ‘Hg’-porosimetry method. The results indicated same nature of pore size distribution pattern in all the 4 samples of different porosity. Pore surface area (m2.g–1) and pore statistics were also studied. |
