Abstract

In this work nanoparticle silica was synthesized using silica sand and quartzite by top down approach using ultrafine grinding. Silica sand was obtained from Bangka island while quartzite rocks from Rokan Hulu, Riau. Both samples have good SiO2 value about 98% and increase up to 99.7% after leached with sulfuric acid in room temperature. The high grade silica then was milled by planetary ball mill in several milling time. The optimum result occured in 30-50 hours milling time produce nanoparticle silica about 80 nm in size. By TEM characterization this nanoparticle looks agglomerated as typical milling product which was caused by Van der Walls’ force between particle after milling process. This nanoparticle silica has good potential for applying in industry, such as for additive materials in ultra high performance concrete for the next development.
