Abstract

This experiment aims to aquire the magnetite nanoparticle by coprecipitation method and also increasing variation of Polyethylene Glycol (PEG) effect on magnetite nanoparticle’s crystal structure. Synthesis had been done by mixing natural sand with HCl as solvent and NaOH as a precipitant, while PEG 1000 and PEG 6000 is added as templates. The addition of each varied from 1:1, 1:2, and 1:3 with a solution of iron salts in order to analyse its influence on the crystal structure of the sample formed. The magnetite nanoparticles resulted in the samples were characterized using X Ray Diffraction instrument to determine the phase formation and the size of the crystals formed. Further it were scanned with Electron-microscope to determine the morphology of the sample. From the characterization acknowledged that the percentage of the volume fraction of the sample were increased. Meanwhile magnetite nanoparticle samples have a face-centered cubic structure, and the crystal fields are in accordance with the JCPDS (Joint Committee Powder Standart) no.19 – 629 with crystal size less than 50 nm. The results showed that the addition of PEG can increase the percentage of the volume fraction of magnetite nanoparticles and does not affect the crystal structure of magnetite nanoparticles.
