    The present article aimed to synthesize spherical silica nanoparticles (SNPs)from rice husk ash as an inorganic product, and  to estimate cost of  the products production.  SNPs were prepared in pilot scale from RHA using optimum operating conditions, resulted from laboratory experiments (2.0 N NaOH, 100 o C, 2h reaction time and  stirring rate 120 rpm). The produced SNPs are c...
