Bismuth (271.3oC)

Bismuth is a silvery-white metallic element with a pinkish tint on freshly-broken surfaces. Bismuth is relatively brittle for a metal. It has the interesting physical property of expanding when freezing to a solid.
Bismuth metal is relatively inert and non-toxic. It has replaced lead in many applications such as plumbing, bullets, birdshot, metal alloys, soldering, and other applications. Some uses for Bismuth are: Used as a mild stabilizer in malleable iron or to improve nodule count in S.G. iron, and some of its other uses include: Fishing weights, Shot gun cartridges, For additions to glass, For additions to the galvanizing process, and the replacement of Lead in some solders and Brass alloys, and the production of low melting point alloys which all have there own individual uses.
Quite interestingly for a heavy metal, Bismuth is scientifically recognized as one of the safest elements. It is also non-carcinogenic. Accordingly, a growing number of industrial applications depend upon it to alleviate specific toxicity or environmental problems.

Uses

In cosmetics as bismuth oxychloride.
In medicine as bismuth subnitrate and subcarbonate.
Bismuth subsalicylate is used as an antidiarrheal.
Strong permanent magnets are made from the alloy bismano (MnBi).
Many alloys of bismuth have low melting points and hence they are used for fire detection and suppression system safety devices.
In producing malleable irons.
In making acrylic fibers.
Used as a thermocouple material.
A carrier for U-235 or U-233 fuel in nuclear reactors.
Used in solders.

Bismuth subnitrate, a component of glazes produces an iridescent luster finish.

In the production of shot and shotgun slugs.
