Characteristic study of SiO2 content of quartz rock as a raw material for making silicon metal for solar cells

Abstract

Abstract Studies on the characterization of quartz rock have been carried out at three locations, namely on the shores of Lake Poso, the Poso River and the location of sand mines has been done using XRF and XRD methods. The results indicate that the SiO2 mineral content obtained from the Poso Lake, Poso Piver and Poso sand mining locations are 99.4%, 99.34% and 99.30%, respectively. The XRD data showing that the Miller index value obtained in all three samples is [101] with a trigonal crystal structure (hexagonal axes).
