The purest metal on earth is platinum. Unlike other metals, it has the ability to retain the highest levels of its purity for as long as three million years. This makes it an ideal metal for jewelry and other products that are designed to last for a lifetime. It is also used in the manufacture of medical devices such as inhalers.
Osmium is one of the rarest elements on earth. It is less reactive than other metals. However, it has very few uses. It is often used in electrical contacts and in nuclear reactors. It is also a component of hard metal alloys. Osmium is used in the production of tungsten carbide inserts in electronic circuit boards. It is also used to make hardcore ball bearings. It is also used as a filler in jewelry. It is also used as a protective coating for nuclear reactor cylinders.
Gold is the purest metal on earth, and it's only been refined to a purity of 999.9 parts per thousand. Unlike silver, which is highly reactive, pure gold is non-irritating and non-toxic. The atomic number 79 makes gold one of the naturally occurring higher atomic number elements. It occurs in a native state, in association with copper deposits, and as a natural alloy. It is also used as a food additive. Some of its compounds are approved for food use by the EU and the Codex Alimentarius. In addition, it is used in electrical wiring for high-energy applications.
In the late twentieth century, two-thirds of the world's gold was produced in four countries: the United States, Australia, South Africa, and Russia. In the 2020s, the world's production amounted to just over a tonne. In addition, a small amount is used in cell phones and almost every sophisticated electronic device.
Platinum is one of the purest metals on Earth. The silvery white metal has a melting point of approximately 3,215 degrees Fahrenheit. Platinum has a wide range of uses. It is used in the chemical and medical industries as well as jewelry. It is also a highly sought after precious metal. It is also widely used in the automotive industry.
Platinum is a member of the platinum group. It is closely related to rhodium and palladium. These metals are also used for applications that require extreme hardness and durability. Platinum has a hardness of 4-4.5 on the Mohs scale. It is resistant to chemical attacks and corrosion in air. It is also malleable. It can be melted and dissolved in hot alkali.
The name "zirconium" comes from a Persian word meaning gold-like. This metal is found in the Earth's crust, mostly in zircon. It has a high melting point of 2550 deg C. It is also found in meteorites. It has an extremely low capture cross section for thermal neutrons. The most important applications of zirconium are in the manufacturing of steel alloys, and in the crucibles and cladding of nuclear reactors. Zirconium can also be found in medical implants.
Ruthenium is one of the rarest elements on Earth. It is an element of the platinum group. It has an atomic number of 44. Despite its rarity, ruthenium is used in a variety of applications. It is particularly useful as a chemical catalyst in industrial processes. It is also used in wear-resistant electrical contacts, making it useful in the electronics industry.
Ru is also an important component in metallurgy, owing to its ability to harden metals and improve their corrosion resistance. It is often alloyed with palladium and platinum. Its alloys are used in the manufacture of a wide range of products. It is also used as a coating on technical applications. It is found naturally in the Ural Mountains of Russia, and it is extracted from the nickel mines in the Sudbury Basin, Ontario, Canada. It is also used in the production of the radioisotope Te-116.
