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.

本文收集了通过球磨和共沉淀法从稻壳灰（RHA）中提取纳米二氧化硅的数据。稻壳灰作为一种广泛分布于印度尼西亚的农业废弃物，其提取物可作为纳米复合材料的填充剂。对稻壳灰进行500°C、5小时的煅烧处理，以实现二氧化硅的提取。随后，在球磨机中以250 rpm的转速进行10小时的球磨。进一步地，将稻壳灰与5 M的盐酸按1:4的比例混合，搅拌并在磁力搅拌器中以70°C的温度加热4小时，转速为400 rpm。之后，再次与氨水按1:4的比例混合，搅拌并在磁力搅拌器中以70°C的温度加热4小时，转速为400 rpm。通过扫描电子显微镜（SEM）、傅里叶变换红外光谱（FTIR）和X射线衍射（XRD）对所得稻壳灰进行了进一步表征。数据显示，从稻壳灰中提取的纳米二氧化硅性能优异，适用于作为纳米复合材料的填充剂。
