• Application: Bismuth is used to make the drugs such as Pepto-Bismol for upset stomachs and diarrheaand in medicine to treat intestinal infections. Bismuth is used in the cosmetics industry toprovide the "shine" for lipsticks, eye shadow, and other products.It is added to steel and other metals as an alloy to make the metals easier to roll, press, pullinto wires, and turn on a lathe. It is also used in the semiconductor industry and to makepermanent magnets.Bismuth is similar to antimony in that it expands from the molten liquid state to the solidstate. This property makes it an excellent material to pour into molds and can produce finedetails in whatever is being molded, such as metallic printing type and similar fine castings.

Case Study

Ultrafine Bismuth Powder for Effectively Improving Zinc Electrode Performance

Da, Yuxin, et al. Journal of Electronic Materials, 2020, 49, 2479-2490.

Adding ultrafine bismuth (Bi) powder to the zinc electrode of zinc-air batteries can improve the performance of zinc-air batteries. When the amount of ultrafine bismuth powder is 1.5 wt.% of zinc powder, the Zn-Bi electrode has the highest anti-corrosion efficiency, reaching 53.8%. After battery assembly, the capacity retention rate of the Zn-Bi electrode reached 84.6% after 60 cycles.
Preparation of Zn-Bi electrodes
· The spherical Zn powders and ultrafine Bi powders were prepared by DC arc plasma evaporation.
· The Zn (0.075 g) and Bi powders (0-3 wt.% of the quantity of Zn powder) were evenly mixed and then stirred at a speed of 200 rpm for 10 min.
· The Zn-Bi powders were evenly mixed with acetylene black, a 60 wt.% PTFE emulsion and a 7.5 wt.% PVA solution, which were 15%, 5% and 5% of the quantity of Zn-Bi powders.
· The mixture was coated on a nickel-plated brass mesh dried at 40C, pressed with pressure of 10 MPa and cut into 2 9 2 cm2 Zn-Bi electrodes.
