Synthesis and Characterization of SiO2 Nanoparticles via Sol-gel Method for Industrial Applications

Synthesis and Characterization of Microwave Absorber SiO2by Sol-Gel Methode

“…Several methods can be employed for the manufacture of SiO 2 , including precipitation [8][9][10], and sol-gel [11][12][13]. The sol-gel method is widely used because the process takes place at low temperature, the simple and the resulting product has a high purity and nanoscale.…”

Synergistic effect of nano‐SiO2 and small‐sized graphene oxide on carbon fiber/epoxy composite

“…Figure C shows the FTIR spectra of nano‐SiO 2 modified by KH550. The band around 823, 1140, 1670, and 3480 cm −1 correspond to the vibration of SiO, the asymmetric stretching vibration of SiOSi band, the flexural vibration of SiH 2 O and the stretching vibration of SiOH . There is also a peak at 1520 cm −1 corresponding to the deformation vibration of NH 2 from silane coupling agent .…”

Synthesis and characterization of hydrophobic nano-silica thin coatings for outdoor insulators

“…The broad peak observed in the pattern of the calcined coating may be assigned to the low crystallite size and defective structure of the dried gel. Dubey et al [16] reported that the broad XRD peak confirms the existence of a high volume percent of non-organic particles in the dried gel. The SiO 2 coating has not been crystallized by calcination at temperatures up to 1200°C, which is in good agreement with the results of other researchers [17].…”
