Sol-gel-derived bioactive calcium silicates, synthesized from calcium nitrate tetrahydrate and calcium 2-methoxyethoxide as calcium precursor respectively, were calcified under different temperatures. A series of techniques including SEM, TGA, solid ²⁹Si NMR, nitrogen adsorption, and simulated body fluids (SBF) soaking were employed to study their textural features and in vitro bioactivity. It was confirmed that calcium 2-methoxyethoxide is a promising candidate of calcium precursor for bioactive calcium silicates stabilized under low temperatures. This has implications in fabrication of organic-inorganic hybrid composites.
