Geothermal sludge is a waste from geothermal power plants (PLTP) with very high silica content. Geothermal sludge waste is potential as a basic material in the synthesis of silica nanoparticles. The research was conducted using FeCl3 salt as Fe ions precursors forming the silica magnetic nanoparticles. This was obtained by reacting silica waste with NaOH 1,5 N at 90 °C, added with 1,6 gr FeCl3 and subsequently adding 2N HCl solution to form a gel at pH 5 and aging for 18 hours. The calcination temperature of the samples were varied at 400°C, 500°C, 600°C and 700°C. Characterization of magnetic silica nanoparticle included Brauner Emmet Teller (BET) to determine the surface area, X-Ray Diffraction (XRD) for phase identification and morphology of the nanoparticles was characterized Transmition Electron Mycroscope (TEM). The results showed that samples calcined at 400 °C was in its amorphous phase and has the highest surface area of 658.11 m2/g.
