What is Bismuth Used For?

Bismuth is a chemical element, with the symbol Bi and atomic number 83 on the periodic table, that has recently grown in popularity due to its fascinating properties. It is a dense, silvery-white heavy metal with a pinkish tint that has a unique combination of low toxicity, and a low melting point. 

Together these characteristics make bismuth a versatile element that is used in cosmetics, pharmaceuticals, electronics, bismuth crystal jewelry, fire prevention products, and more. In this blog post, we will touch on where bismuth comes from and explore its various uses. 

Bismuth is a unique elemental substance that continues to find surprising new applications. It has an amazing capacity for versatility, and depending on the form it takes, can be put to use in a variety of ways.

Bismuth salts, like bismuth subsalicylate, bismuth subsulfate and basic bismuth carbonate, are frequently used in antacids and stomach medicines. 

As an active ingredient in products like Pepto-Bismol, bismuth subsalicylate works by coating the lining of both the stomach and the intestines, which reduces inflammation and relieves symptoms associated with digestive ailments such as nausea, vomiting, and diarrhea. Along with its anti-inflammatory properties, bismuth subsalicylate also has an antimicrobial effect that curbs the proliferation of certain bacterial strains like E. coli and Salmonella.

Bismuth oxychloride is a chemical compound often found as a white crystalline powder, and it is commonly used in the cosmetics industry as a pearlescent pigment. Bismuth oxychloride gives cosmetics products such as lipsticks, eyeshadows, and nail polishes a shimmery, pearl-like finish that creates the appearance of depth and dimension. Bismuth oxychloride is also used in cosmetics to add bulk to a product and give it an attractive sheen.

Another reason bismuth oxychloride has become so popular in cosmetics is because it is non-toxic and hypoallergenic. Unlike other pearlescent pigments such as mica, bismuth oxychloride does not cause irritation or allergic reactions, a great benefit for those with sensitive skin. As such, bismuth oxychloride is FDA approved for use in cosmetics products, meaning users can enjoy its range of benefits without compromising on safety.

Bismuth compounds are a powerful and useful tool in the manufacturing process of certain materials. Bismuth compounds act as catalysts, allowing for chemical reactions to occur at a much faster rate while not being consumed in the process. Bismuth compounds are employed most commonly in the polymerization process, which is used in the creation of synthetic fibers and rubber.

In the case of synthetic fibers, the bismuth compound catalyzes the polymerization of synthetic monomers such as polyethylene, polypropylene, and polyamide, which are the building blocks of synthetic fibers such as nylon and polyester. This helps speed up the process and produce fibers with improved properties like strength and elasticity. Similarly, bismuth compounds are also used to make synthetic rubber and give it its characteristic elasticity and durability.

Bismuth metal is becoming increasingly popular for creating unique and captivating jewelry designs. Pure bismuth metal has a relatively low melting point, which allows it to be cast into a variety of shapes and forms. This makes it an ideal choice for crafting intricate pieces. Bismuth can be alloyed with other metals such as tin, which can help create vivid and eye-catching crystal formations. Bismuth adds an exquisite visual effect to rings, necklaces, and other pieces of jewelry due to its shiny, rainbow sheen.

Bismuth crystals and jewelry are made by melting pure bismuth and then casting it into a mold to form various shapes and sizes. When the bismuth has cooled and solidified, it acquires its rainbow colors through oxidation. The surface of the bismuth is heated in an oxygen-rich environment, which causes the surface of the bismuth to oxidize and form a layer of bismuth oxide. The bismuth oxide layer has a different crystal structure than the underlying bismuth and reflects light differently, creating the rainbow hues.

The same process that is used to create low-melting alloys for bismuth jewelry is also used to make bismuth-tin solder for various plumbing and electronics applications. In plumbing, it is used to join copper pipes and fittings because it is non-toxic and does not contribute to lead contamination in drinking water. As it pertains to electronics like computers, mobile phones, and televisions, bismuth is used to join electronic components to printed circuit boards and other electronic assemblies

As you can see, bismuth and bismuth alloys are versatile materials with a wide range of uses across many industries. Its unique properties make it useful in everything from cosmetics to electronics.
