Effect of the Calcination Atmosphere on the Structural Properties of the Reduced Fe/SiO2 System,ied the influence of the calcination atmosphere (air or nitrogen) on the iron oxide reducibility and the metallic iron particle size obtained in Fe/SiO. system. We have impregnated a silicagel with Fe(NO.). · 9H.O aqueous solution and the solid obtained was calcinated in air or N2 stream. These prec

,NMR and Mössbauer Study of Al2O3-Eu2O3,e prepared by the sol-gel technique. The XRD patterns for the calcined samples show a broad peak around 2θ = 30° which is assigned to the Eu.O.; after treatment with hydrogen at 1073 K no reduction to Eu. or Eu. was observed. The NMR spectra show three peaks, which are assigned to the octahedral, pe

,Hydrometallurgical Extraction of Zinc and Copper — A 57Fe-Mössbauer and XRD Approach,g process. In the present investigation a zinc-copper ore from the Maranda mine, located in the Murchison Greenstone Belt, South Africa, containing sphalerite (ZnS) and chalcopyrite (CuFeS.), was studied. The .Fe-Mössbauer spectrum of the concentrate yielded pyrite, chalcopyrite and clinochlore, con

,Structural and Electronic Properties Study of Colombian Aurifer Soils by Mössbauer Spectroscopy anderous samples are from the El Diamante mine, located in Guachavez-Narinño (Colombia) and were prepared by means of polished thin sections. The petrography analysis registered the presence, in different percentages that depend on the sample, of pyrite, quartz, arsenopyirite, sphalerite, chalcopyrite
