Abstract

The synthesis and characterization of magnetic materials pseudobrookite Fe2TiO5 from local resources of iron sand has been performed. Iron sand mineral is obtained from the coast of Banten. Iron sand is prepared by mechanical milling technique to obtain a small particle size. Then sand iron is carried out leaching and magnetic seperator to separates non-magnetic impurities. And then the separation results with magnetic separator is added TiO2 according to the rules of stoichiometric tomade magneticmaterial pseudobrookite Fe2TiO5. Synthesis of pseudobrookite Fe2TiO5 use solid state reaction through a process of mechanical milling and sintered at a temperature of 1000 °C for 5 hours. Refinement results of X-Ray Diffraction pattern showed that the magnetic material pseudobrookite Fe2TiO5 has been formed of good with the crystal structure of orthorombic (space group C m c m), lattice parameters a = 3.7233(5) Å, b = 9.774(1) Å and c = 9.968(1) Å, α = β = γ = 90o, the unit cell volume of V = 362.8(1) Å3 and atomic density of ρ = 4.178 g.cm-3. The measurement results of the magnetic properties indicate that the pseudobrookite Fe2TiO5 is soft magnet, and had coercivity field and remanence magnetization are 461 Oe and 0.2 emu/g, respectively. We concluded that this study has successfully made a magnetic material pseudobrookite Fe2TiO5 from local resources of iron sands.Keywords: Iron sand, Magnet, Pseudobrookite, Fe2TiO5, Crystal structure, Microstructure
