A pinkish-white metal in its purest state, bismuth (Bi) quickly tarnishes to a brownish-grey color when exposed to the atmosphere. While rarely used in an un-alloyed state, high-purity bismuth is key in producing alloys with a minimum of unexpected impurities, and thus consistent repeatability.
Bismuth in metal form is fairly brittle and has a relatively low melt point. While this sounds like a flaw, it makes metal bismuth a high value alternative to toxic metals with similar traits, such as lead.
- Low-melt alloys. Bismuth is a common component in low-melt alloys, such as those used for soldering. In more demanding applications, high purity becomes important—even minor flaws in a mix can be significant in high-precision applications.
- Lead substitute. Bismuth, like gallium and other malleable, low-melt metals, is one of the metals used frequently as a non-toxic alternative to lead. As lead usage in end-user products drops, bismuth usage increases.
- Electrical applications. Used to produce alloys and compounds for high-end thermoelectrical materials and superconductors.
- Reactor coolants. A key component in many reactor cooling systems, often as part of an alloy with lead. High purity materials are crucial in reactor safety systems, as unexpected impurities can lead to unexpected results.
