Influence of calcination temperature on the morphology and magnetic properties of Ni–Zn ferrite applied as an electromagnetic energy absorber

“…The combustion reaction method is described in detail by Costa et al [7]. The powders were calcined at 800, 1000 and 1200 • C/2 h. The powders before and after calcinations were characterized by X-ray diffraction (XRD), using a SHIMADZU diffractometer (XRD 6000 model, with Cu K␣ radiation).…”

“…Tel. : +55 83 3310 1178; fax: +55 83 3310 1178. allows for the production of powders of nanosized particles with a large surface area and a high degree of purity [6]. The work therefore aimed to evaluate the structure, morphology and electromagnetic absorption properties of Ni-Zn ferrite powders obtained by combustion reaction, before and after calcinations at temperatures of 800, 1000 and 1200 • C/2 h, for are application as materials for absorbing electromagnetic energy.…”

Combustion synthesis of cobalt ferrite nanoparticles—Influence of fuel to oxidizer ratio

“…Among various methods for synthesizing ferrites, the combustion method stands out as an alternative and highly promising method [9]. Though co-precipitation is known for synthesis of fine cobalt ferrite nanoparticles, it does require careful control upon pH of the solution, concentration and temperature like parameters.…”

Role of Cr3+ ions on the microstructure development, and magnetic phase evolution of Ni0.7Zn0.3Fe2O4 ferrite nanoparticles

“…However, we have not found any reports in the literature on Ni-Zn ferrite powders obtained by combustion reactions. Combustion synthesis, which is employed in the field of propellants and explosives, involves an exothermic and self-sustaining chemical reaction between the desired metal salts and a suitable organic fuel [18]. A key feature of the process is that the heat required to trigger the chemical reaction is provided by the reaction itself and not by an external source, such as urea [19].…”
