A Novel Low‐Temperature Synthesis of Nanosized NiZn Ferrite

Abstract

Nanosized NiZn ferrite powder is synthesized by a low-temperature method, using a unique combination of citric acid and glycine. An appropriate molar ratio of both citric acid and glycine offers a low-temperature synthetic route by incorporating the complexation behavior of citric acid and the combustion nature of glycine. Thermal decomposition/controlled autocatalytic combustion of the composite gel occurs at a low temperature of around 1751C, with the evolution of a large amount of gases. Transmission electron microscopic studies showed that the average particle size of the ferrite obtained is B2.5 nm, with a narrow size distribution. Uniformly distributed fine-grained microstructure with low porosity is obtained for a sample sintered at 10001C.

The Effect of Milling Time on Ni0.5Zn0.5Fe2O4 Compositional Evolution and Particle Size Distribution

“…4 and 5) of milling are smaller than the crystallite size obtained from the XRD pattern implies that the particles exist as nonporous aggregates, due to their high surface energy [6] . From the XRD spectra in Fig.…”

Combustion synthesis of Co-doped zinc oxide nanoparticles using mixture of citric acid–glycine fuels

“…All amine group-contained fuels decompose at relatively low temperatures [18]. Accordingly, an appropriate mixture of citric acid and glycine would be the best choice to use both of the complexing ability of citric acid and the combustion nature of glycine [19].…”

Magnetic and dielectric properties of mixed spinel Ni–Zn ferrites synthesized by citrate–nitrate combustion method

“…Ni-Zn ferrite is mainly used in high-frequency applications [4]. Recent interest in the study of several ferrites is in terms of their synthesis and sintering at low temperatures as well as on nanosized ferrite materials for various applications [5][6][7][8][9][10][11].…”
