The optimization of natural resources of local indonesian materials to synthesize magnetic and magnetic hybrid particles via chemical ablation, co-precipitation, and hydrothermal route process

The magnetic nano-particle synthesized from natural iron sand had been successfully done. Generally, this natural iron sand is a kind of natural waste in Indonesia that has not been optimally used. This research is expected to explain the utilization of Indonesian local natural iron sand as an advanced magnetic material resource. Therefore the reader of this article can develop it for further application. Magnetic particles are a material that is very promising in supporting developments of science and technology. One of them is the development in medical fields. Most previous researchers carried out the magnetic synthesis of particles using chemicals as precursors. In this study, the researchers would like to report how to synthesize magnetic particles using local natural iron sand. The applied method consisted of three steps, namely chemical ablation, co-precipitation, and hydrothermal method. The results of this research showed that Zn-dopped magnetic particles in Quasi-spherical structures become hollow-microsphere morphological structures even though they had not been perfected yet. The Zn-dopped treatment broadens the frequency wave absorptions and magnetism properties. The Zn-dopped Ion had stronger magnetic properties than that of organic factor effects from C-dot that theoretically can decrease the magnetic properties. This article briefly describes the synthesis mechanism of magnetic material from natural iron sand as material resources to substitute highly expensive mainstream chemical material. However, this study still needs to be deeply investigated to produce the optimum scientific application. (paper)
