Synthesis of nanosilicone has been carried out from natural sand with magnesiothermic method. Silica from natural sand was extracted by sodium hydroxide 10 N and hydrochloride acid 6N. Ultrasonication of silica with potasium chloride has been done with ratio of SiO2:KCl (1:7.5 and 1:12.5). Silica converted to silicone by magnesiothermic methode with ratio SiO2:Mg = 1:2, heated up to 800 C for 6 h. Nanosilicone was purified with deionized water and ethanol, HCl 5 N and HF 10%. The result of XRD analysis of nanosilicone of ratio SiO2: KCl (1:7.5 and 1: 12.5) each 88.8% and 73.0%. The disrtibution of particle size wer 28.56 nm - 170.57 nm and 12.70 nm -93.32 nm. Photo SEM Of particle nanosilicone shows a pore and agglomeration.
