Rice‐shaped bioactive ceramic nanoparticles of 70 nm average diameter and around 200 nm length were produced by an improved sol‐gel method. In comparison to most traditional bioactive glass/ceramic materials, this novel bioactive ceramic contains a significant lower quantity of silicon and higher content of phosphorous. In vitro bioactivity tests showed that this new class of materials can induce the deposition of an apatite layer from simulated body fluid, having the potential to be used in both conventional orthopedic applications or in bone tissue engineering when incorporated in composite scaffolds.
