The reoxidation rate of sponge iron pellets and briquettes and oxidation of pure iron powder with compressibility between 27% and 55% in air and within the temperature range 300-900°C has been investigated. Factors affecting the oxidation rate are presented. These include the effect of temperature, compressibility, and sintering of Fe-powder before and during the oxidation.

   Magnetic iron oxide nanoparticles have numerous applications in the biomedical field. This paper reports the preparation and properties of iron oxide nanoparticles synthesised by thermal decomposition method from iron chelates. The iron oxide nanoparticles were characterized by FTIR, powder XRD, VSM, SEM and TEM techniques. FTIR and powder XRD studies show that iron oxide was fo...

Starting materials used were 99.8% pure nickel, 99.9% pure iron, 99.9% pure tantalum, and 99.9% pure molybdenum. The materials in a total weight of 500g were melted with a high-frequency induction furnace in vacuum. The melt was poured into an iron mold with an opening of 20mm diameter and 150mm length. After forging, the ingot was reduced to a thin plate 0.3mm in thickness by rolling and a wir...

differential diagnosis of iron-deficiency anemia and beta-thalassemia, two common causes of anemia, affects the treatment in pregnant women. to help the diagnosis, we have tried to asses the pure effect of gestation on diagnostic criteria, eliminating iron and folate deficiency. in a prospective study, 46 thalassemic women were given ferrous sulphate tablets and folate. some indices, cbc and hb...

Oxidation of ferritic/martensitic steel P92 was investigated in pure oxygen and in pure steam at 600-800 °C by thermogravimetric analysis (TGA), optical microscopy (OM), scanning electron microscopy (SEM), and X-ray diffraction (XRD). The results showed that the oxidation of P92 was significantly enhanced and multilayer scale with an outer iron oxides layer formed in pure steam. At 700 °C, the ...

BACKGROUND Anemia of chronic disease (ACD) and iron deficiency anemia (IDA) are the two most prevalent forms of anemia having interrelated characteristics. Hepcidin, a newly introduced biomarker for assessment of iron status, is a homeostatic regulator of iron metabolism. We investigated the role of hepcidin and other conventional iron parameters to assess iron status among children with ACD an...
