Si‐doped hydroxyapatite nanoparticles (n‐ S i x HA ) were prepared by hydrothermal synthesis from calcium nitrate tetrahydrate and diammonium hydrogen orthophosphate. A rod‐like morphology was obtained for all the powders irrespective of the incorporated S i‐doping level. But the crystallinity of the n‐ S i x HA powders, the density achieved upon sintering powder compacts and their mechanical properties (three‐point‐bending strength), as well as their biomineralization activity evaluated by immersing them into simulated body fluid ( SBF ) were found to be dependent on the S i‐doping amount.
