Abstract

Synthesis of Fe3O4 particles was performed using coprecipitation method. Iron sand base material obtained by processing the iron rocks by means of destruction and extraction. Iron rocks were taken from the village Surian, South Solok of West Sumatera. Iron sand that has been extracted reacted with HCL and NH4OH. Furthermore, the PEG-2000 were added to see its effect on the resulting magnetization saturation. Variations in the composition ratio of iron sand and PEG-2000 are 1:0, 1:1, 1:2 and 1:4. The crystal structure of the sample was confirm using x-ray diffraction method. Characterization of magnetic properties carried out using vibrating Sample Magnetometer (VSM). The results of magnetic properties show that the saturation magnetization decreases with increasing of PEG-2000 content in the range of 99.50emu/g - 0,84 emu/g.

Keywords
