History. Bismuth evidently was known in very early times, since it occurs in the native state as well as in compounds.For a long period, however, it was not clearly recognized as a separate metal, having been confused with such metals as lead, antimony, and tin.Miners during the Middle Ages apparently believed bismuth to be a stage in the …

Simplifier - Bismuth Alloy Thermocouple. Thermoelectricity is the phenomenon by which a thermal gradient produces a voltage gradient within a conductor, and of all the conductive elements, bismuth exhibits this effect to the greatest degree. Furthermore, certain additives are capable of modifying this effect in bismuth, most notably antimony ...

However, their progresses are prevented by the inferior cycling performance caused by severe volumetric change and pulverization during the (de)sodiation process. To address this issue, herein an alloying strategy was proposed and nanoporous bismuth (Bi)–antimony (Sb) alloys were fabricated by dealloying of ternary Mg-based precursors.

Abstract. We have performed spin- and angle-resolved photoemission spectroscopy of antimony (Sb) and bismuth (Bi) thin films grown on Si (111) to elucidate the nature of the Rashba effect in the spin-split surface bands. In Sb, we revealed spin polarization with the in-plane vortical texture on an elongated hole-like Fermi surface.

The development of alloy-type anodes is one of the promising strategies to address this issue. In this work, the electrochemical properties of bismuth-antimony-tin (Bi–Sb–Sn) alloy anodes for MIBs have been studied. Bi–Sb–Sn alloys with varied compositions have been synthesized using the mechanical alloying method.

The two elements, bismuth (Bi) and antimony (Sb), are both in Group 15 (pnictogen) of the Periodic Table [5,6]. Bismuth is the heaviest element of this group and is often referred to as a "green" metal due to its benign nature and low toxicity compared to the other group 15 elements such as arsenic and antimony [5].

Bismuth telluride Bi 2 Te 3 consists of heavy atoms; that is one of the reasons for its high thermoelectric efficiency. Crystal structure of Bi 2 Te 3 (Fig. 1.1, left) is characterized by rhombohedral actual primitive cell (Fig. 1.1, top right).Lattice constant c of the rhombohedral cell (between bottom and top points) equals to approximately 5.08 …

Antimony and bismuth are two of the most problematic impurities in copper electrorefining. As a result, much research has been done investigating the ways to remove them. Processes that are currently being used industrially include anode additions, liberators, ion exchange (IX), and solvent extraction (SX). Of these, liberators and anode …

Arsenic and antimony are classed as metalloids or semimetals, and bismuth is a typical β subgroup (post-transition element) metal like tin and lead. This chapter further discusses the abundance, distribution, and extraction of arsenic, antimony, and bismuth. None of the three elements is particularly abundant in the earth's crust although ...

Here, we assess a series of bismuth/antimony oxyhalides and chalcohalides using consistent first principles methods to ascertain their properties and obtain trends.
