Summary: The aim of this work was to obtain pseudowollastonite‐based ceramics and to determine its bioactive features. The materials were obtained by new method, namely thermal treatment of ceramic active fillers‐containing polysiloxane polymeric precursor. As active fillers, commercially available Ca(OH) 2 and silica nanopowders (SiO 2 ) were used. The phase composition of ceramic products were analysed by the means of Fourier transform infrared spectroscopy (FTIR) and X‐ray diffraction analysis (XRD). The microstructure of ceramic products were studied by scanning electron microscopy (SEM) with EDS point analysis. The bioactivity was determined in “in vitro” conditions, by immersing of ceramic samples in simulated body fluid (SBF). The results presented in this work indicate that heat treatment of active fillers‐containing polysiloxane precursor is an alternative method for receiving of pseudowollastonite‐containing materials. Such obtained samples demonstrate bioactivity in “in vitro” conditions.
