In the present study, the powders of biphasic calcium phosphate were synthesized by decomposing monetite in aqueous solutions containing Ca2+, NH4+ and NO32- ions. The green biphasic calcium phosphate ceramics were prepared by cold isostatic pressing of the chemical powders. Controlled porosity in the green and sintered ceramic was obtained by using naphthalene-PMMA beads custom-made within the size range 200 to 400 microns. The ceramics were sintered by firing the organic-free compacts at temperatures ranging from 1000 to 1200 degreesC Pore size and pore size distribution in the sintered ceramics were evaluated by SEM analyses. In the porous artificial bone, the average pore size meets the requirements for natural bone ingrowth.
