Abstract

Hematite (Fe2O3) has been synthesized from iron sand using the copresipitation method. This study aims to determine the morphology and mineral content using SEM EDX, crystal structure and phases formed using XRD, and magnetic properties using VSM on iron sand before and after synthesis. SEM EDX result show that the average particle size of iron sand before and after synthesizing is 356.23nm and 12.40 micrometer, respectively. XRD results show that iron sand before synthesizing has miltiphase including hematite, Magnetic, Ilmenite and after synthesizing produces single phase hematite. VSM results show that iron sand before synthesizing has saturation, remanace, and coercivity of 47.56 emu/g, 5.97 emu/g, 121.03 Oe respectively and after synthesizing has saturation, remanace, and coercivity of 9.47 emu/g, 1.53emu/g and 102.97 Oe respectively.
