Morphology‐Enhanced Low‐Temperature Sintering of Nanocrystalline Hydroxyapatite

By using hydroxyapatite (HA) nanorods, dense (> 99 % theoretical) HA nanocrystalline (see figure) bioceramics were attained at 850 °C through morphology-enhanced diffusion as the driving force for densification. This new mechanism has the potential to give advanced ceramics with enhanced properties or new functionalities.
