CHECK LISTSodium silicate solution (containing around 8% Na2O and 28% SiO2), Ammonia Solution, Ethanol, Deionized Water, RB Flask, Magnetic stirrer, Centrifuge
-
STEP 1.Add 1ml Sodium silicate in 15ml water.
-
STEP 2.Make second solution by mixing 90ml Ammonia and 30ml Ethanol.
-
STEP 3.Add Sodium Silicate solution (prepared in step-1) drop wide into Ammonia+Ethanol solution (prepared in step-2).
-
STEP 4.After 1 hour of aging, wash and centrifuge the formed product. Finally dry it to get Silica Nanoparticles powder.
-
RESULTSSize of the formed Silica Nanoparticles should be around 80nm. Broad peak around 24 two theta should be observed in XRD. FTIR consist of peaks at 1094–1100 cm−1 for Si–O–Si; and the band at 466–470 cm−1 for Si–O–Si.

NOTE: All the experiments should be done under the guidance of lab Incharge; and proper lab safety instructions.
