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 800ºC 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.
