Ca-hydroxyapatite powder was prepared by wet chemical route. The powder was calcined (900 deg C) and added with various amounts of pore former to produce four different mixes. All were pressed cold isostatically (150MPa) and debinded to remove pore former from the structure. The fragile structures thus obtained were sintered (1250 deg C) 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 four samples of different porosity.
