Abstract
Abstract The purpose of this study is to synthesize and characterize of iron sand from the south coastal area of Purworejo, Central Java. Iron sand was mechanically filtered using permanent magnets 35 times. The filtered iron sand was characterized using x-ray diffraction (XRD) to determine the compound contained therein and his physical characteristics. The filtered iron sand was heated at temperatures of 800 ° C and 900 ° C for 5 hours in the furnace and after it was cold and followed by XRD testing. Based on the x-ray diffraction pattern, a single phase Fe 2 O 3 as a permanent magnet base can be formed after a 900 ° C heating process for 5 hours.
