Synthesis and characterisation of the compound CoSbS

In the search for new intermetallic materials with high thermoelectric performances, the Co-Sb-S ternary system has been explored and polycrystalline CoSbS samples have been prepared by a vapour phase technique starting from the pure elements. The crystal cell of CoSbS belongs to the Pbca space group and shows an orthorhombic structural arrangement with the following lattice parameters: a = 5.8341(2) A b = 5.9477(2) A, and c = 11.6540(4) A. The structure belongs to the pyrite-marcasite family, as Co forms tilted corner- and edge-sharing octahedra with three Sb and three S atoms. Scanning electronic microscopy (SEM), electron-probe microanalysis (EPMA) and X-ray powder diffraction were used to investigate the microstructure and to carry out the structural analysis; the crystal structure was refined by the Rietveld method using the DBWS-9807 program. The thermal stability of CoSbS was investigated referring to the ternary Co-S-Sb phase diagram and by differential thermal analysis (DTA) measurements. Thermoelectric power measurements at room temperature were also performed by a home-made instrument.

Thermodynamic and kinetic analysis for carbothermal reduction process of CoSb alloy powders used as anode for lithium ion batteries

Thermodynamic calculation and kinetic analysis were performed on the carbothermal reduction process of Co3O4-Sb 2O3-C system to clarify the reaction mechanism and synthesize pure CoSb powder for the anode material of secondary lithium-ion batteries. The addition of carbon amount and thus the purity of CoSb powders were critical to the electrochemical property of CoSb anode. It was revealed that in an inert atmosphere, Co3O4 was preferentially reduced to CoO, followed by the reduction of Sb2O3 and CoO. CO2 was the gas product for the reduction of Co 3O4 and Sb2O3, while CO was the gas product for that of CoO. Based on the analysis result, pure CoSb powder without any oxides and residual carbon was synthesized, which showed a higher specific capacity and a lower initial irreversible capacity loss, compared to CoSb sample with residual carbon. This work can be a reference for other carbothermal reduction systems.

Refinement of the Microwave-Assisted Polyol Process for the Low-Temperature Synthesis of Intermetallic Nanoparticles

The microwave-assisted polyol process was applied to synthesize phase-pure micro- or nanocrystalline intermetallic phases in the systems T–M (T = Co, Ni, Rh, Pd, Ir, Pt and M = Sn, Sb, Pb, Bi). Reaction temperatures range between 240 and 300 °C, and reaction times of a few minutes up to 1 h are sufficient. For optimization of the syntheses, the reaction temperature, reaction time, and metal precursors were changed. To obtain phase-pure samples the process was further modified by the addition of potassium hydroxide, oleylamine, or oleic acid. Single-phase powders of a variety of intermetallic compounds were synthesized. Although not stable at the temperature of synthesis, high-temperature phases are accessible as well. The microwave-assisted polyol process opens up the possibility to synthesize intermetallic compounds through a fast and easily applicable one-step route, without utilization of strong and often toxic reducing agents.

Synthesis and characterization of mono- and di-antimonide with the first transition metals in group 8B by mechanical alloying

Mono- and di-anitimonide compounds between antimony and the first transition metals in group 8B were synthesized by mechanical alloying method. All samples were investigated by the X-ray powder diffraction technique and differential thermal analysis. The single phase can be obtained only for CoSb, NiSb and CoSb2 compounds. In this investigation, a single phase of a marcasite structure (FeSb2 and NiSb2) and Fe 0.56Sb0.44 compound cannot be detected in the XRD patterns after 60 h of milling because of the instability of their structures at low temperature. They decomposed to their starting materials as seen by the characteristic peaks of the starting materials in the XRD patterns after 60 h of milling.
