Extraction of Silica (SiO2) from White Sand, Sulawesi Island
Abstract:
The natural resources of the coastal sands of North Sulawesi are very potential and need to be explored and developed. Sand is composed of compounds based on the location of the sand along the coast. The potential of beach sand, namely Si (Silicon) can be a basic material such as SiC (Silicon Carbide) functional materials, semiconductors, and others. The first stage is sampling of white sand at several points and varying sand depths. Furthermore, the white sand is cleaned of impurities and iron sand. The second stage is sand preparation, sand identification and the third stage is silica extraction using the Alkali Fusion method using a high concentration base. Testing of elemental composition using XRF (X-ray Fluorescence), crystal structure using X-Ray Diffraction, and functional groups using Fourier Transform Infrared. The results of XRF analysis show that beach sand is composed of chemical compositions with a chemical component of CaO > 80%, the results of XRD analysis show that Silica (SiO2) compounds are in the form of quartz and show the Si-O functional group.
