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

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.本数据集包含通过球磨法与共沉淀法从稻壳灰（rice husk ash）中提取纳米二氧化硅（nano silica）的相关实验数据。稻壳灰是印度尼西亚广泛分布的农业废弃物，提取得到的纳米二氧化硅可作为纳米复合材料的填充剂。先将稻壳灰置于500℃下煅烧5小时以提取二氧化硅；随后将煅烧后的稻壳灰放入球磨机，以250转/分钟的转速研磨10小时。将研磨后的稻壳灰与5M盐酸按1:4的比例混合，使用磁力搅拌器以400转/分钟的转速搅拌，并在70℃下加热4小时；之后再次将混合物与NH4OH（浓度为M）按1:4的比例混合，于70℃、400转/分钟的转速下使用磁力搅拌器加热搅拌4小时。所制得的样品随后通过扫描电子显微镜（Scanning Electron Microscope，SEM）、傅里叶变换红外光谱（Fourier-transform infrared spectroscopy，FTIR）以及X射线衍射（X-ray diffraction，XRD）进行表征。实验数据表明，从稻壳灰中提取的纳米二氧化硅性能最优，可作为纳米复合材料的填充剂使用。
