Abstract
This article consists of data from the extraction of nano silica from rice husk ash (RHA) by ball mill and coprecipitation methods. RHA is an agricultural waste that is widely found in Indonesia. The extracted RHA can be used as a filler in nanocomposites. Calcining RHA did silica extraction from rice husk ash at 500 °C for 5 h. After calcining RHA in the Ball Mill for 10 h with a rotation of 250 rpm. Furthermore, RHA was mixed with 5 M HCl in a ratio of 1:4, stirred, and heated with a Magnetic Stirrer at 70 °C for 4 h at a speed of 400 rpm. Then mixed again with NH(4)OH M in a ratio of 1:4, stirred, and heated with a Magnetic Stirrer at a temperature of 70 °C for 4 h at a speed of 400 rpm. The resulting RHA was further characterized by Scanning Electron Microscope (SEM), Fourier-transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD). The data shows that nano silica from RHA is optimal and can be used as a filler in nanocomposites.
