Bismuth expands % on solidification. This property makes bismuth alloys particularly suited to the making of sharp castings of objects subject to damage by high temperatures. With other metals such as tin, cadmium, etc., bismuth forms low-melting alloys which are extensively used for safety devices in fire detection and extinguishing systems.

Bismuth is a common ingredient in pharmaceuticals, although as more and more information is known about it, its usage is decreasing. Bismuth subsalicylate is used as an anti-inflammatory and an antacid, which is used to neutralize stomach acidity. A very common example of this is Pepto-Bismol, which is "pink bismuth" that is used to treaty.

The electronic excitations of the low‐valence bismuth cluster cations Bi53+, Bi82+, and Bi95+ have been studied with experimental and theoretical techniques. The UV‐visible spectra of the bismuth ions were measured in acidic chloroaluminate melts (mixture of 1‐methyl‐3‐benzyl imidazolium chloride and AlCl3).

Transient spectroscopic studies (from ps to s) show that the bimolecular recombination of photogenerated electrons and holes in NCNCNx can be well described by a random walk model. Remarkably, the addition of hole scavengers such as 4-methylbenzyl alcohol can lead to ∼fold faster recombination kinetics (lifetime shortening to ∼10 ps).

Bismuth is one of very few metals that expands as it freezes. It has the highest resistance to being magnetized of all metals, as well as a high electrical resistance, and is second only to mercury in low thermal conductivity. An extremely stable element, it is believed that percent of the bismuth present at the "birth" of the universe.
Elemental bismuth occurs as metallic crystals associated with nickel, cobalt, silver, tin, and uranium sulphide ores. Bismuth is found in the ores bismuthinite (Bi 2 S 3), bismite (α-Bi 2 O 3), and bismutite [(BiO) 2 CO 3] from Peru, Japan, Mexico, Bolivia, England, Norway, Brazil, and is more usual to recover it as a by-product from lead and copper smelting plants.

The spectroscopic properties (SPs) of bismuth glasses are strongly influenced by the preparation conditions. Here, we studied the effects of melting temperature and concentration ratio of Bi2O3 to SiO2 on the SPs of Er3+ doped Bi2O3-B2O3-SiO2 bismuth glasses.
We have shown that the low melting temperature is preferable to achieve large and broad gain of Er3+ ions. The correlation between bismuth and uranyl staining and phosphorus content of intracellular structures as determined by electron spectroscopic imaging.

This, in turn, is due to the difficulty in studying the complex chemistry of this element. Bismuth undergoes hydrolysis from below pH 1 and forms precipitates around pH 2 already, thus has to be studied from low pH.
