A Facile Synthesis And Characterization Of Amorphous Silica (Sio2) By Thermal Treatment Route

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.
