RHA use in silica gel production. Silica gel is a rigid threedimensional network of colloidal silica. It is classified as aquagel (pores are filled with water), xerogel (aqueous phase in the pores is removed by evaporation) or aerogel (solvent is removed by supercritical extraction). Silica aquagel is also called as silica hyrogel.

Silica nanoparticles (SNPs) consist of several applications which include lightweight aggregates, energy storage, and drug delivery. Nevertheless, the silica reagents used in SNP synthesis are both costly and hazardous. As a result, it is critical to look for other sources of silica. For this research, a simple solgel hydrothermal approach is used to make SNPs from South African fly ash (SAFA).
