Calcium Nitrate
Calcium nitrate was dissolved in 100 ml ethanol and magnetically stirred in order to obtain a clear solution.TEOS was first hydrolyzed (molar ratio TEOS:water = 1:4) and then added to the solution. This solution was agitated (magnetically stirred) for 1 h at 60 °C and then kept at 60 °C for up to 72 h to facilitate the alcohol evaporation and to accelerate the polycondensation reaction; the ...
