Currently, silica is produced by autoclaving the quartz sand (sand stone) with strong alkali solution to form silicate solution, and subsequently forming silica gel by adding acid to lower the pH to <10. ( Iler, 1979; Seki et al., 1987; Tsugeno et al., 1993; Iosef, 1995; Guo et al., 2003; Wason, 1976.
Pickling is to soak the carrier with 6mol/L hydrochloric acid for 2 hours or heat and soak with concentrated hydrochloric acid for 30 minutes, filter, wash with water to neutrality, and dry. 2. A lot of fine powder will also occur during the process of silica sand making, which will affect the purity of silica sand products.
