Abstract |
Here we report synthesis and characterization of chemically synthesized calcium hydroxide (Ca(OH)2)
with and without deliberate presence of NaNO3 as an impurity. Calcium nitrate tetrahydrate
(Ca(NO3)2.4H2O) is used as precursor and alkaline NaOH solution is used as precipitant to synthesize the
Ca(OH)2 samples. The samples were characterized by XRD, FESEM, FTIR spectroscopy, DTA, TGA and
UV-Vis spectroscopy techniques. From the UV-Vis spectroscopy results, it is found that the Ca(OH)2 with
NaNO3 impurity has higher bandgap than the sample without NaNO3. The weight loss in TGA is also more
for the Ca(OH)2 with impurity than the one for without impurity. The results are discussed in terms of
composition formed during synthesis process. |
