Abstract

It has recently been investigated that ball milling can improve the magnetic properties of natural iron sand significantly. In this work, we present the phase composition and magnetic behavior of iron sand from Syiah Kuala Beach, Banda Aceh. Samples were prepared by mechanical alloying method using a Fritsch planetary ball mill for 20 hours. As the results, it was shown by XRD testthat Fe3O4 (magnetite) appears as the majority phase and the magnetic properties observation shown that the magnetization saturation (Ms) and remanent (Br) was decreased with the increasing of the coercivity (Hc).

Abstract

The observation on reactive mechanical alloying (RMA) process had been done to form MgH2 material with adding Ni nanoparticles as catalist for hydrogen storage material applications. Pressure and temperature of material forming were recorded by microcontroller set for 30 minutes. Mg with adding Ni 5 wt % was milled by High Energy Ball Mill (HEBM) at H2 atmosphere in 1 atm of pressure. The measurement results showed that the pressure had been changed and temperature also changes up to 38oC. This process proves that the alloying betwen Mg and H2 had been formed. The X-ray diffraction pattern identify MgH2 phase. SEM image showed the morphology of MgH2 particles.
