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...

Highly stoichiometric zinc ferrous ferrites Zn,F+,O, were prepared and characterized by magnetization, desacwmmodation, electrical conductivity, thermal expansion and magnetostriction measurements. The results of the magnetization measurements indicate that up till x = 0.5 the magnetic structure is collinear, which led to the highest saturation magnetizations ever found in spinel femtes. The th...

Gossan ore of sulfide zinc deposit contains abundant zinc, iron, and other metal elements, which is a significant resource with complex components can be utilized. In this study, new technology preparing ferrite from gossan was proposed. The effects Al2O3, CaO, SiO2 in on the formation were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), specific surface area pore s...

HIsarna reactor is characterized by a high raw materials versatility and therefore attractive for processing secondary iron sources. Among the that can be recycled through HIsarna, zinc-bearing material has drawn special attention. Based on plant data, once dust-containing Zinc was injected into main reactor, final collected dust with zinc content of 16% achieved which opened up possibilities h...
