| Abstract: | Various kinds of calcium oxides, carbonates and phosphates were used as the raw materials, and β-TCP ceramics was fabricated by reaction sintering at 1100 °C, and the sinterability, the reaction sintering behavior and mechanical properties of reaction-sintered β-TCP were investigated. Reaction-sintered bodies using CaHPO4 + HAp consisted of single β-TCP phase, and bulk density and bending strength increased with extending sintering time. On the contrary, normal-sintered β-TCP synthesized using CaHPO4 + HAp did not change in bulk density and bending strength with extending sintering time. Reaction-sintered body using CaHPO4 + HAp as the raw materials showed higher bulk density and bending strength than normal sintered β-TCP. |
