In this letter, we present a new approach to the synthesis of silicocarnotite ― a promising bioceramic material. This approach is based on selecting a precursor with a crystalline structure close to that of silicocarnotite in an attempt to reduce the transformation temperatures. In the synthesis route that we suggest, silicocarnotite forms from mechanochemically synthesized nanosized silicon-substituted apatite. The main advantages of this route are lower temperatures and shorter annealing times required for the synthesis of the target phase in comparison with the direct solid-state synthesis, aqueous precipitation or sol–gel method. It was shown that the silicocarnotite phase is obtainable by annealing the mechanochemically synthesized silicon-substituted apatite for 5 h at a temperature as low as 1000 °C. According to the differential scanning calorimetry, the phase transition from silicon-substituted apatite to silicocarnotite occurs at 970 °C. In this work, complete assignment of the absorption bands of the IR spectrum of silicocarnotite to particular bond vibrations is reported for the first time.
