12052-42-5 Usage

Chemical Properties

hexagonal crystal(s); 6mm pieces and smaller with 99.5% purity [CER91] [LID94]

Uses

Skutterudites such as Cobalt antimonides are widely studied as a promising thermoelectric (TE) material for high-temperature applications. The thermoelectric power of the cobalt antimonides can be further improved by suitable doping or by filling the interstitial voids with guest atoms and also by nanostructuring.In recent years CoSb is also used as electrode material for lithium ion batteries.

General Description

This product has been enhanced for energy efficiency.

Check Digit Verification of cas no

The CAS Registry Mumber 12052-42-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,5 and 2 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 12052-42:
(7*1)+(6*2)+(5*0)+(4*5)+(3*2)+(2*4)+(1*2)=55
55 % 10 = 5
So 12052-42-5 is a valid CAS Registry Number.

The isothermal section of the Ce-Co-Sb ternary system at 400 °C

Luo,Liu,Li,Feng

, p. 60 - 63 (2009)

Phase equilibria were established in the Ce-Co-Sb ternary system at 400 °C based on X-ray powder diffraction (XRD), scanning electron microscopy (SEM) and energy dispersion spectroscopy (EDS) techniques. Fourteen binary compounds Ce24Co11

Synthesis and characterisation of the compound CoSbS

Carlini,Artini,Borzone,Masini,Zanicchi,Costa

, p. 23 - 27 (2011)

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

Yang, Jianying,Wang, Mengwei,Zhu, Yuntong,Zhao, Hailei,Wang, Ronglin,Chen, Jingbo

, p. 7657 - 7661 (2011)

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

Teichert, Johannes,Heise, Martin,Chang, Jen-Hui,Ruck, Michael

supporting information, p. 4930 - 4938 (2017/11/21)

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.

Reductive synthesis of metal antimonides

Kift, Rebecca L.,Prior, Timothy J.

, p. 428 - 433 (2011/01/08)

A new low temperature synthetic route to binary and ternary metal antimonides is reported. Binary transition metal antimonides prepared include CoSb3, CoSb2, CoSb, NiSb, NiSb2, Cu 2Sb and Mo3Sb7; new ternary compositions prepared include the series Co1-xNixSb (0.1 ≤ x ≤ 0.9). The intermetallic SnSb has also been prepared by this route. The synthetic method is simple and does not require the use of very high temperatures, multi-step reactions or reaction under vacuum. Compounds were synthesised by the reduction of mixed metal oxides under 10% hydrogen in argon at moderate temperatures (approx. 450 °C). The route affords some control over the stoichiometry of the product. High purity binary phases formed include CoSb 3, CoSb, NiSb, Cu2Sb and SnSb. Owing to the significantly different reduction temperatures of the starting metal oxides, Mo 3Sb7 was formed with impurities of MoO2 and Sb metal. CoSb2 and NiSb2 were formed with impurities of CoSb3 and NiSb, respectively.
