Investigations on physical properties of Mg ferrite nanoparticles for microwave applications

The Potential of Fe‐Based Magnetic Nanomaterials for the Agriculture Sector

“…Recently, magnesium oxide (MgO) NPs have received much attention from researchers because they are eco‐friendly, economically competitive, and industrially important NPs [247] . The physiochemical behaviours of MgO NPs such as possessing excellent refractive index, [248] low electrical conductivity, [249] superior corrosion resistance, [250] high thermal conductivity, [251] mechanical strength, flame and dielectric resistance, outstanding optical transparency and stability, have made them an ideal material for various applications in for both industrial and environmental remediations [252] . For instance, MgO NPs were able to remove organic dyes such as methyl orange, methylene blue, congo red, methyl red and reactive black dye effectively because of the large active specific surface area, high specificity and reactivity [253] .…”

Investigation of the catalytic effect of nano ferrite CoCuNiFe2O4 on the thermal decomposition behavior of ammonium nitrate

“…26 The medium sharp peak at 1030 cm −1 was assigned to metal oxygen lattice vibrations. 27 The peak at the frequency range of 550–700 cm −1 proves the stretching vibration of the metal-oxide bond. The bands at 547.8 cm −1 and 592.2 cm −1 corresponded to stretching vibrations in octahedral and tetrahedral sites, respectively.…”

Effect of Calcination Temperature on Physical properties of Ni0.6Zn0.4Fe2O4 Ferrite nanoparticles

“…illustrates the changing of dielectric constant with increasing frequency calcined at 400 0 , 500 0 C and 600 0 C. The enhancement of dielectric constant with calcination temperature is mainly due to that more Ni 2+ ions occupy A sites instead of Fe 3+ ions. Hence, the number of Fe 3+ ions migrate to B site, causes more concentration of Fe 3+ ↔ Fe 2+ ion pairs at the B-site and consequently the amount of space charge polarization increases, leads to increase the values of dielectric constant [21].…”
