“…Synthesis of BaM with Zn doping (BaFe12-xZnxO19) using coprecipitation method based on natural iron sand at the Tebing Beach of North Lombok as a microwave absorbent material has been successfully carried out. The materials used in this study were magnetite (Fe3O4) obtained from iron sand, BaCO3 as a holder, Zn as a doping, HCl as a solvent, distilled water (H2O) as a diluent and NH4OH as a precipitant (Susilawati et al, 2022). BaM synthesis was carried out using 3 variations of doping concentration (x), namely x = 0.000; 0.400; and 0.800.…”

This study aims to synthesize barium M-hexaferite using the coprecipitation method with Zn doping based on natural iron sand at the Tebing Beach of North Lombok as a microwave absorbent material. This study used 3 variations of doping concentration (x), namely x = 0.000; 0.400; and 0.800. In addition, variations in the calcination temperature were also carried out, namely 400°C and 1100°C. After the calcination stage, the sample is ground to obtain smaller or nano-sized particles. The results showed that the sample has a brick red color for a temperature of 400°C and black for a temperature of 1100°C. This shows that the higher the calcination temperature, the darker the color of the sample.

“…Hematite (α-Fe2O3) has properties that are difficult to corrode so it is suitable for applications such as gas sensors, catalysts, lithium-ion batteries, and pigments, it can also be used in the manufacture of permanent magnets. At high temperatures, the α-Fe (Edianta et al, 2021;Gandha et al, 2016;Miftahul Khoiroh et al, 2013;Rostami et al, 2021;Suhendi et al, 2021;Susilawati et al, 2022).

Iron sand, which contains magnetite iron ore, exhibits unique magnetic properties when exposed to magnetic fields. Iron ore content, including ?-Fe2O3, FeTiO3, Magnetite (Fe3O4), and others, provides potential uses in various industries such as electronics, energy, chemical, ferrofluids, catalysts, and biomedicine. The location of the discovery of iron sand can affect its mineral characteristics and geological conditions. This research aims to develop innovative synthesis methods to produce hematite nanomaterials from iron sand. Nano-size hematite nanoparticles exhibit unique characteristics, including an increase in specific surface area that is beneficial in applications such as gas sensors, catalysts, lithium-ion batteries, and the manufacture of permanent magnets. Through a literature review, this article presents comprehensive insights into the characteristics of iron sand, variations in synthesis methods, and the structure of hematite nanoparticles. Applications of hematite nanoparticles in water treatment, catalysis, and energy storage are also detailed. This article is expected to contribute to the development of innovative nanomaterial technologies as well as explore the potential of iron sand resources for wider industrial applications.

Fe3O4 nanoparticles made from the natural iron sands of the Gelar River have been successfully synthesized using the coprecipitation method. Test the content of Fe elements in pure iron sand and characterize them using XRF after separation. Fe3O4 nanoparticle characterization uses XRD to determine the sample's lattice parameters and crystal size. The nanoparticles' morphology, structure, particle shape, and elemental content were characterized using SEM-E DX. Magnetic properties and magnetic saturation values are characterized using VSM. XRF yield on iron sand before separation contains Fe 59.46%. After separation, the Fe content rose to 84.72%. The synthesis results obtained brownish-black Fe3O4 nanoparticle powder that permanent magnets can attract. Based on the XRD results, the crystal structure formed is cubic inverse spinel with crystal lattice Å with a particle size of 14.8 nm. The SEM-EDX results show the morphology of spherical nanoparticles with multiple agglomerations. Particle size is 40 nm. The EDX spectrum confirmed the formation of Fe3O4 nanoparticles in the presence of Fe (51.79%) and O (25.68%). The VSM results show that Fe3O4 samples have ferromagnetic properties with saturation magnetization (MS) = 27.36 emu/g, remanent magnetization (Mr) = -0.01 emu/g, and coercivity field (Hc) = 0.01 T.
