A Study of Nanocrystalline Cobalt Prepared by Ball Milling
The hcp-fcc transformation induced in cobalt powder by ball milling at room temperature was studied using the excess Gibbs free energy for the metals, in nanometric form, to calculate the activation barriers that the atoms must overcome for the phase transformation to occur. The crystalline component of the nanocrystaline cobalt produced in our laboratory, via ball milling, was analized using t...
متن کاملMicrostructure characterization and cation distribution of nanocrystalline magnesium ferrite prepared by ball milling
Nanocrystalline magnesium ferrite is synthesized by high-energy ball milling. The formation of nanocrystalline ferrite phase is observed after 3 h of milling and its content increases with milling time. The structural and microstructural evolution of the nanophase have been studied by X-ray powder diffraction and the Rietveld method. After 3 h of milling, ferrite phase (mixed spinel) nucleates ...
متن کاملMicrostructural Characterization of Calcite-Based Powder Materials Prepared by Planetary Ball Milling
In this work, a planetary ball milling was used to modify the surface properties of calcite-based material from waste oyster shell under the rotational speed of 200-600 rpm, grinding time of 5-180 min and sample mass of 1-10 g. The milling significantly changed the microstructural properties of the calcite-based minerals (i.e., surface area, pore volume, true density, and porosity). The surface...
متن کاملUrban leakage of liquefied petroleum gas and its impact on Mexico city air quality.
Alkane hydrocarbons (propane, isobutane, and n-butane) from liquefied petroleum gas (LPG) are present in major quantities throughout Mexico City air because of leakage of the unburned gas from numerous urban sources. These hydrocarbons, together with olefinic minor LPG components, furnish substantial amounts of hydroxyl radical reactivity, a major precursor to formation of the ozone component o...
متن کاملSolubility Study in Ag-Cu Binary System Prepared By Ball Milling Process
Solid solutions of Ag-Cu were prepared via ball milling process, for about 5-30 h. The Cu-20at%Ag and Cu-3.64at%Ag composition were investigated by X-ray diffraction technique. It was realized that the solid solubility level could be increased by increasing the initial solute content in the mixture. In addition, shifts in peak positions of silver and copper were observed with milling time. The ...
