On-Site Speaker (Planned)
Abstract Scope This work is a first step on the way to characterize raw sandstone in Jordan, and to extract silica and silicon for the use in solar cells and other industries. Seven samples of raw sandstone were brought from Disi in Jordan. The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR), and X-ray fluorescence (XRF). The XRD diffractograms showed that silica is the main constituent of the samples, and two samples contain Kaolinite Al2(Si2O5)(OH)4. EDS reports showed that all samples contain aluminum and carbon, but some of them contain calcium. XRF measurements revealed that some samples contain more than 97% silica, while one sample contains more than 90% silica, and the main impurity is Al2O3. FTIR revealed the known bands of silica, and this sandstone is free of organic compounds impurities.
