Highly dispersed powders containing α‐tricalcium phosphate as the main constituent, produced by a sol‐gel process and subsequent heating to at least 1300°C, exhibit hydraulic properties if allowed to react with water. Both pastes and compacts made from such powders exhibit setting and hardening, especially in the presence of sodium phosphate, potassium phosphate, and ammonium phosphate, which act as catalysts. The product of the hydration process is hydroxy‐apatite in combination with a C‐S‐H and/or C‐S‐P‐H gel.
