In this work, substituted lanthanum manganites with calcium and strontium, La0.7Ca0.3-xSrxMnO3 (x = 0, 0.1, 0.2, 0.3), were prepared by a high-energy ball milling method and their microstructure and magnetotransport properties were studied. The raw materials were Mn2O3, La2O3, CaO and SrO, mixed in the stoichiometric ratio to obtain these manganites. The mechanical activation process was perfor...
Abstract Taguchi’s method was applied to investigate the effect of main high energy ball milling (HEBM) parameters: time (MT), powder weight ratio (BPWR), and speed (MS) on CaCO 3 crystallite size. The settings HEBM parameters were determined by using L9 (3 ) orthogonal experiments array (OA). as-received milled powders characterized X-ray diffraction (XRD) scanning electron microscopy (SEM), F...
Ball-milled graphitic carbon, both not and electrochemically lithiated, has been studied by total x-ray diffraction involving high-energy synchrotron radiation scattering and atomic pair distribution function analysis. The experimental data has been used to guide reverse Monte Carlo simulations of the three-dimensional structure of the not-lithiated samples. Experimental and modeling results sh...
