[ 1 ] - Chemical Synthesis of Nano-Crystalline Nickel-Zinc Ferrite as a Magnetic Pigment
The nano-crystalline nickel-zinc ferrite was prepared via chemical synthesis. Zinc nitrate, nickel nitrate, iron nitrate hydrate, citric acid and ethylene glycol were used as precursor materials. Crystallization behavior of the precursor was studied by X-ray diffraction (XRD). Nanoparticle phases can change amorphous to spinel ferrite depending on the calcination temperature and crystallite siz...
