• A new type of calcium phosphate (CP) paste that retains plasticity during kneading and sets promptly under a physiological condition was successfully prepared by mixing Ca4O(PO4)2 (TTCP) and CaHPO4 (DCPA) (CP powders) at 67 mass % with a gelatinized wheat starch. This paste retained plasticity because the gelatinized starch layer on the surfaces of the CP particles suppressed the rapid reaction between the CP powders. When the paste was soaked in a tris-buffered NaCl solution (TRIS), the starch layer loosened and the reaction between CP powders to form hydroxyapatite (HAp) took place at a considerable rate. The setting was found to start at 5 hours after the soaking in TRIS and proceed from the surface to the interior portion of the paste. The maximum compressive strength, 5.7 MPa which is close to that of human cancellous bone, was attained. All the pastes containing CP powders prepared in this study formed bone-like apatite on their surfaces within 1 day after being soaked in a simulated body fluid (SBF, at 310 K), independent of the CP powders content. These pastes can be stored retaining the plasticity as desired even after 3 weeks in vacuo under a cool (∼277 K) condition without precipitating HAp. This material is expected to be one of the candidates for an easy-handling and highly bioactive calcium phosphate bone paste.
