In this study, we used silica sand as a source of sodium silicate solution (eq. 1) and controlled the formation of silica nanoparticles with HNO 3 using the sol–gel method. The formation of silica nanoparticles was based on the reaction of the sodium silicate solution with HNO 3 as shown by eq. 2 and the white fine powder of silica ...

It has been previously demonstrated that the addition of milling auxiliaries such as silica gel has been shown to provide significant rate enhancements of mechanochemical processes [13–17]. However, it is poorly understood how silica gel can speed up certain reactions and how to fully take advantage of this strategy in a …
