Abstract
Highly dispersed powders containing alpha-tricalcium phosphate as the main constituent, produced by a sol-gel process and subsequent heating to at least 1300 degrees C, exhibit hydraulic properties if allowed t o react with water. Both pastes and compacts made from such powders ex hibit setting and hardening, especially in the presence of sodium phos phate, potassium phosphate, and ammonium phosphate, which act as catal ysts. The product of the hydration process is hydrorxy-apatite in comb ination with a C-S-H and/or C-S-P-H gel.
