A Dealloying Synthetic Strategy for Nanoporous Bismuth–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.

Antimony and Bismuth Control in Copper Electrolyte by Ion …
Antimony and bismuth are two of the elements that need to be removed from copper electrolyte to ensure a trouble free operation as well as to maintain copper cathode purity. One method to control these impurities is the use of aminophosphonic ion exchange resins. Antimony is present as both Sb(III) and Sb(V).

The meltings under pressure of arsenic, antimony, and bismuth have been determined up to nearly 70 kbar by means of differential thermal analysis (DTA). Arsenic initially melts with a positive dT/dP, the fusion curve flattening out near 940°C at the highest pressures attained. The fusion curve of antimony exhibits practically no change with pressure …

Carbene chemistry of arsenic, antimony, and bismuth: …
The larger atomic size of bismuth causes it to have poorer orbital overlap with the carbene centre than its lighter congeners. Additionally, due to its metallic nature, organo-bismuth compounds exhibit significantly different reactivity and stability. Therefore, the synthesis of carbene-stabilized bismuth species is even more challenging.
