Preparation Of Nanoparticle Silica From Silica Sand and ...

2013-7-12  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.

2016-10-27  The purification of silica sand is usually conducted in order to obtain a required high silica percentage and minimal impurities. However, the impurities in the residue still become the obstruction to obtaining a high purity of silica. An experimental investigation was conducted to explore the purifying process via the ball milling technique, followed by an ultrasonic bath. In this study, the concept of Taguchi’s Design of Experiments was applied in order to optimize the processing parameters used to purify Tronoh silica sand. The results reveal that the important parameters influencing the ball milling process were duration of milling, jar volume and ball per powder weight ratio (BPR). At the same time, the results also show the concentration of NaOH, soaking time and ultrasonic temperature were important factors for ultrasonic bath. Therefore, improvements in the purification of the silica sand process
