  • The effect of the gelation time in the chemical reaction to change the phase from sol to gel on the gel and quartz powder states was investigated by observing the absorbance spectra of the gels and powders at wavenumbers of 500–4000 cm−1. In the case of the gel state, four peaks appeared in the absorbance spectrum, i.e., a broad OH stretching peak at 3000–3700 cm−1 derived from the OH group, an OH bending peak at ~1640 cm−1, an asymmetric Si−O−Si stretching (VasSi−O−Si) peak at ~1075 cm−1, and a The gel-pulverizing process on the morphology of the as-synthesized quartz powders. Three hours after the ion exchange process, SiO2 sol was changed into a single lump of gel; when subjected to the gel-pulverizing process, the gel lump was separated into many gel lumps of several mm.
