Porous ceramics of calcium hydroxyapatite with non-stoichiometric composition were prepared hydrothermally. The hydroxyapatite ceramics prepared at 105¸C under the saturated vapor pressure for 20 h were composed of rod-shaped crystals with about 10 μm in length with the mean aspect ratio of 40. The porous ceramics of calcium deficient hydroxyapatite had about 50% porosity with the inter-connecting pore structure. This porous ceramics had compressive strength of about 10MPa. According to the in vitro test, this calcium deficient hydroxyapatite must be the bio-active material.
