Pptd. silica having a surface area of 50-400 $m^2/g$ and a tap d. of 80-600 $kg/m^3$ is manufd. from rice husk ash by digesting insol. silica present in the rice husk ash with NaOH at 70-95 Deg for 1-3 h to produce sodium silicate, pptg. silica by reaction of sodium silicate with $CO_2$ at a gauge pressure from atm. to 3.5 $kg/cm^2$, followed by filtration, drying, and pulverization of the silica. NaOH is regenerated by reacting the formed $Na_2CO_3$ with CaO or $Ca(OH)_2$ at 80-95 Deg.
