摘要

This study presents the hydrothermal synthesis of hematite (α-Fe₂O₃) nanoparticles with controlled morphological variations, including rhombohedral, irregular, and Nano plate structures. The phase purity and crystallographic structure of the synthesized samples were validated using X-ray diffraction, confirming the successful formation of hematite. Detailed transmission electron microscopy analysis revealed pronounced differences in particle shape and size, emphasizing the effectiveness of the synthesis method in tailoring morphology. Magnetic properties were systematically investigated using a superconducting quantum interference device magnetometer, demonstrating a clear correlation between nanoparticle morphology and magnetic response. The results collectively show that particle morphology plays a substantial role in determining both the structural and magnetic behavior of hematite nanoparticles. These findings contribute to the rational design and engineering of nanomaterials for advanced technological applications.
