Although bismuth was added by the Incas to a specific type of bronze alloy-cutting tool, it was not fully understood. It was frequently confused with silver, lead, and tin. Bismuth, which is Latin for “white substance”, comes from German. However, the metal bismuth doesn’t always look silvery-white. It also contains some pink. Jofroy & Bergman in England confirmed Bismuth to be a chemical element only in 1753.
Bismuth has a metallic sheen of peach-colored white. It emits yellow smoke from its flames, which produce a blue flame. Bismuth has an extremely low melting point of 271°. It is possible to melt bismuth in a small stainless steel pot at home and let it cool down. The bismuth actually expands upon freezing, much like water. A partial oxidation of its surface results in a rainbow-colored collection of crystals. This is due to different thicknesses of the oxide film on the bismuth crystal top.

What is bismuth like to gold?
It is twice as common as gold in the earth’s crust, and one of the most rare metals. It is the number83 element in a periodic table and the heavyest element. It is relatively inexpensive at a mere few dollars per kilogram in the international market. It is extremely affordable compared to other fossil material.
Bismuth was used to make boxes and other boxes in ancient Greece, Rome and beyond.

How does bismuth achieve its iridescent sheen appearance?
Due to the spiral-step structure in the bismuth crystals, the oxide film around its outer edge grows at an increased rate. It will interfere with light. Bismuth is often found as free metal and minerals in nature. When scientists heat bismuth to a high temperature, they can create bismuth oxide. This happens when the liquid is dissolved into bismuth. The polarized light rainbow that results from cooling the silver becomes bismuth. Complex and regular bismuth crystals are possible. Its color can be determined by how thick the outer oxide layer is, which reflects different metal colors. It is sometimes compared to lead which is often replaced with bismuth.

Why bismuth?
Bismuth has a density similar to lead, but is less toxic than the former. Lead can cause kidney damage and headaches. Many children were killed by lead poisoning. Foreign hunters often replace the lead bullets in their hunting rifles by ammunition made of bismuth. Bismuth is used for killing animals.

Bismuth’s thermal and electrical conductivity are low. Bismuth has a melting temperature of 271.5 degrees Celsius.
Bismuth crystals shine brighter than diamonds, and can be transformed into many arts and crafts. Bismuth can also be used in cutting edge technologies such as superconductors, nuclear testing, and other applications.

The University of Delaware published a study that found a unique property of the metal bismuth. This can be used as an accelerator to convert carbon dioxide into liquid fuels or industrial chemicals. The team behind the project believes that this discovery could lead to a reduction in carbon dioxide emissions as well as a sustainable method of fuel production.
Researchers call this new bismuth characteristic “catalytic plasticity.” The researchers have previously demonstrated that bismuth films can also be combined with certain liquids to make carbon monoxide gaseous fuel. The new study concluded that electrifying bismuth film in salt solutions containing imidine ions and amidines ions regulates chemical reaction that convert carbon dioxide into industrial chemical formic acids or liquid fuel gasoline.
According to general theory, chemical reactions can require different catalysts. But the “catalyticplasticity” of bismuth means that the metal bismuth is able to catalyze many kinds of chemical reactions. Researchers pointed out that technical aspects of the new findings, which made use of renewable energy sources like wind power and solar energy to promote direct production, metal bismuth catalyst plasticity, make researchers open a new work direction test. Researchers are expected develop renewable energy conversion, a new method of fuel production, and catalytic.
