“…68,69 Apparently, the annealing temperature plays a central role in this method, and the outcome shows that the crystalline Fe 2 O 3 nanoparticles 70 and the dielectric properties are enhanced. 71 Additionally, this technique can be used to create products with efficient physical characteristics, such as low UV absorption and thermal expansion coefficient and high optical transparency. 72 The crystalline structure, composition, purity, magnetism, and morphology of iron oxide nanomaterials can be enhanced by optimizing some variables or combining techniques (Table 4).…”
