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 ~(29)Si 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.
