One of the most valuable metals in the world is Indium. It is soft and indigo colored. In its pure form, it is white and docile. Another extremely valuable metal is silver.
It is bright and white in its pure form is the best electrical and heat conductor, which has the lowest resistance. Silver is used for various purposes, like to protect a mobile phone from a concentration of batteries.
Rhenium is not as popular as gold and platinum, but it is one of the densest metals and has the third highest melting point. Rhenium was discovered in 1925 and is used in high temperature engines.
Palladium is one of the most popular metals, unlike Rhenium. In 1803 William Hyde Wollaston discovered how to separate palladium from platinum ore.
This metal is valued for its resistance to high temperatures, and it has the ability to absorb large amounts of hydrogen.
Palladium is named after Greek goddesses Pallas. Its valuable properties are used in the automotive industry.
Osmium is one of the densest materials on our globe, it is bluish-silver in color and was discovered in 1803 by Smithson Tennant. He is the man who discovered iridium too.
It is a rare metal. Its price is about 12, 700 dollars per kilogram. It has a high melting point and is difficult to handle. When processing osmium, the human eye may suffer.
Ruthenium was discovered in 1844 by Karl Klaus. It melts at 800 degrees Celsius. It is used in electronics and electrical engineering.
Gold has been valued since the time of the ancient Egyptians. Because of its plasticity, it is the most popular metal. Besides for jewelry, it is also used in electrical engineering.
Platinum has the second highest value after rhodium. While one kilogram of platinum worth 38, 290 dollars, one kilogram rhodium worth 46, 516 dollars. It resists corrosion.
