A Facile Synthesis And Characterization Of Amorphous Silica (Sio2) By Thermal Treatment Route
Abstract
A facile thermal treatment route was for the first time used to successfully synthesizeamorphous SiO2
nanoparticles. Various techniques were employed to study the structural, phase and elemental composition of the material at
different calcination temperature of 500 and 550oC. The XRD analysis confirms the formation of SiO2 to be in an amorphous
state and further revealed that the sample remained in amorphous state even at 550oC. While the FTIR shows that the
calcination has enable the removal organic source from PVP and formation of amorphous SiO2 nanoparticles. The average
particle size of the material estimated from the TEM images shows that the particle were <10nm. The EDX analysis has
confirm that there was no loss of element in the process therefore thermal treatment method is effect for the synthesis of
amorphous silica nanoparticles.
