# Data Extraction of Nano Silica as a potential filler in nanocomposites from Rice Husk Ash with Ballmill and Coprecipitation Methods

## Description

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 500oC for 5 hours. After calcining RHA in the Ball Mill for 10 hours 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 oC for 4 hours at a speed of 400 rpm. Then mixed again with NH4OH M in a ratio of 1:4, stirred, and heated with a Magnetic Stirrer at a temperature of 70 oC for 4 hours 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 resulting data shows that nano silica from RHA is optimal and can be used as a filler in nanocomposites.
