Catalysis, nanostructure and macroscopic property triangle in bioactive calcium-containing ceramic systems

► We developed a new sol-gel route for synthesis of bulk calcium silicate bioceramics. ► Ceramics offer low solubility and good mechanical strength for long-term implantation. ► The catalyst has the strongest influence on the ceramic structure and properties. ► Simulated body fluid studies confirmed the bioactive nature of these calcium silicate ceramics.
