A novel route to prepare and characterize Sn–Bi nanoparticles

Media effects on nanobrass arc fabrications

“…Changing the composition of these nanoalloys can drastically impact their properties (such as magnetic strength, conductivity, and surface chemistry), so careful attention must be paid to the synthetic methods and control of morphology. In recent years, many methods have been developed for the preparation of nanoalloy materials including: Metal evaporation, grinding of bulk metal, sputtering, organometallic precursor decomposition [18,19], ball milling (BM) [20], solution phase metal salt reduction [21,22], crystallization of noncrystallinestate [23], pulsed electro deposition [24,25], laser vaporization controlled condensation (LVCC) [26], sonochemical method [27,28], mechanical synthesis [29], template synthesis [30], ␥-ray irradiation [31], metal carbonyl pyrolysis [32], sandblast-annealing [33], laser ablation [34], and co-hydrogenolysis [35]. In particular, colloids of nanobrass alloys (␣/␤-CuZn) as well as colloidal solutions of nanocopper are obtained by co-hydrogenolysis of [CpCu(PMe 3 )] and [ZnCp * 2 ] in the presence of poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) [35].…”

Investigation of preparation and characteristics of Sn–Bi eutectic powders derived from a high shear mechanical approach

“…No visible XRD peak arising from an impurity phase, such as SnO and Bi 2 O 3 , were found. This finding indicated that the sample formed was a Sn/Bi alloy [26]. The lattice parameters for Sn and Bi were essentially similar with those of the bulk alloy, indicating that the as-prepared Sn-Bi alloy particles were mechanical mixtures of pure elements.…”

“…Kao and Duh [25] have used this MA method to investigate the effect of Cu concentration on the microstructure of ternary Sn-Ag-Cu solder powders. Chen et al [26] have synthesized Sn-Bi particles in a monodispersed form by a sonochemical method. Jiang et al [27] have reported the preparation of Sn-In solder particles and 0925-8388/$ -see front matter © 2011 Elsevier B.V. All rights reserved.…”

Fracture Characterization in Enhanced Geothermal Systems by Wellbore and Reservoir Analysis

“…To perform the synthesis, Sn and Bi were melted together at the eutectic composition (~60 wt % Bi and ~40 wt % Sn). After the alloy was cooled to room temperature, 100 mg was sonicated in 10 ml of mineral oil, a slight variation of the sonochemical method suggested by Chen (2005). The VC-505 ultrasonic processor manufactured by Sonics & Materials, Inc. with a 0.75 in.…”
