Thermodynamic analysis of zinc ferrite (ZnFe<sub>2</sub>O<sub>4</sub>) formation inside the HIsarna off-gas system

چکیده
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 higher enrichment direct reuse in Zn smelting as source an alternative ore (the primary source). However vapor react oxide to form ferrite (ZnFe2O4), undesired product. Hence, focus this study minimize formation ZnFe2O using thermodynamic (FactSage) computational fluid dynamic tools. After detecting regions potential ZnFe2O4 formation, proper geometrical operational modifications off-gas system proposed ferrite.

Low Temperature Heat Capacity and Thermodynamic Properties of Zinc Ferrite*
The heat capacity of zinc ferrite (ZnFe,O,) has been determined over the range 5 to 350°K. Molal values of C~,S’, and HO-H,O computed from the thermal data are 32,99&t-0.03 cal/deg., 36.01 f0.03 cal/deg., and 18,00&0.02 Cal, respectively, at 298,lS”K. A co-operative thermal anomaly associated with antiferromagnetic ordering occurs at 9.5” and extends toward higher temperatures probably as a con...
متن کاملThe Zinc-Ferro Ferrite System Revisited
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...

Co3W2Si intermetallic compound was synthesized by mechanical alloying (MA) of W, Co and Si elemental powder mixtures. The phase composition of the milled products was evaluated by X-ray diffraction (XRD) analysis. Morphological evolutions were characterized by transmission electron microscopy (TEM). The results showed that high energy ball milling performed in the present work led to the format...
