Abstract
In this work silicon dioxide (SiO2) was synthesized from rice husk as raw material. The sodium peroxide (Na2O2) influence as precursor on the catalytic activity of the final product was investigated. α-cristobalite and tridymite phases of SiO2 were matched by X-Ray Diffraction (XRD) and analyzed by Fourier Transform Infrared (FTIR), Raman Spectroscopy (RS), Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS). The XRD Rietveld Refinement showed few changes as function of sodium peroxide added during the processing. The content of tridymite phase determined in the samples, was diminished from 19.3% to 8.5%. The main α-cristobalite SiO2 phase was identified from XRD, FTIR and RS spectra, while EDS results showed characteristic energy peaks due to the presence of oxygen and silicon, as expected. Particles and cavities in micrometric range were observed at the samples by SEM. However, smooth surfaces were well defined in other samples. The final morphology depending on the amount of sodium peroxide added. The SiO2 produced powder is suitable for the processing of silicon, silicon oxide as well as silicon nitrides thin films.
