    • Mössbauer and X-ray study of the Fe 65 Ni 35 invar alloy obtained by mechanical alloying 

      Rodriguez Jacobo, Ruby Rocio; Valenzuela, J. L; Tabares Giraldo, Jesús Anselmo; Pérez Alcázar, German Antonio (Universidad Autónoma de Occidente, 2013-03-13)
      Fe65Ni35 samples were prepared by mechanical alloying (MA) with milling times of 5, 6, 7, 10 and 11 h, using a ball mass to powder mass ratio of 20:1 and at 280 rpm. The samples were characterized by X-ray diffraction (XRD) ...
    • Solid state synthesis of Bi0.4Sr0.6FeO3 powder for SOFC applications 

      Rico Castro, Monica María; Rodriguez Jacobo, Ruby Rocio; Medina Barreto, Milton Humberto; Giraldo Betancur, A. L.; Cruz Munoz, Beatriz; Tabares Giraldo, Jesús Anselmo; Munoz Saldana, J.; Benitez Castro, A. M.; Zapata, V. H. (Springer International Publishing, 2017-05-18)
      We report on the synthesis of Bi0.4Sr0.6FeO3 powder with cubic structure by solid state reaction (mechanical milling and calcination) from Bi2O3, SrCO3 and Fe2O3 stoichiometric ratios. Milled powder mixtures were heat ...
