    [abstract] => The study was conducted to recover SiO2 from rice husk ash (RHA) by the hydrolysis of RHA in an alkaline environment. The parameters of the alkaline hydrolysis including NaOH concentration, heating temperature, and heating time were also assessed to develop a more efficient SiO2 reclamation method. The concentrations of NaOH were varied from 1.0 mol/l - 5.0 mol/l while the heating temperatures were changed from 600C - 1000C, and the heating time was ranged from 1 hour - 5 hours. Research results show that the optimization was found at 4.0 mol/l NaOH, 1000C, and 3 hours. The specific surface area of the final SiO2 product  according to data obtained from BET surface area analysis was 152.6711 m2/g, and SiO2 existed in the amorphous form.
