The effects of mass variation potassium chloride (KCl) on characteristics of nanosilicone from natural sand through the magnesiothermic method

Abstract

Synthesis of Nanosilicon has been carried out from Natural sand with magnesiothermic method. Silica of natural sand was extracted by NaOH 10 N and HCl 6 N. Ultrasonication of silica with KCl has been done with a ratio of SiO2:KCl (1: 7.5 and 1: 12.5). Continuosly, silica converted to nanosilicon by using magnesiaothermic method with a ratio of SiO2: Mg 1: 2 heated up to 800C for 6 h. Nanosilicon was purified with deionized water and ethanol, HCl 5 N and HF 10%. The results of XRD analysis of nanosilicon of ratio of SiO2:KCl (1: 7.5 and 1: 12.5) each 88.8% and 73.0% by using Match aplication. The distribution of particle sizes were determined by using Scherrer's equations 28.56 nm - 170.57 nm and 12.70 nm - 93.32 nm.
