Iridium is one of the rarest elements in the earth’s crust.

Is iridium a rare earth metal?

Iridium is one of the rarest elements in the earth’s crust.

Where is iridium found in the world?

Iridium-containing ores are found in South Africa and Alaska, U.S., as well as in Myanmar (Burma), Brazil, Russia, and Australia. In the late 20th century South Africa was the world’s major producer of iridium.

What is mercury used for?

Mercury is used primarily for the manufacture of industrial chemicals or for electrical and electronic applications. It is used in some liquid-in-glass thermometers, especially those used to measure high temperatures.

How do you remove iridium from gold?

Iridium and ruthenium can be separated from gold by dipping the adulterated Gold in Aqua Regia (mixture of hydrochloric acid and nitric acid). Aqua Regia will dissolve Gold, but Iridium and Ruthenium will remain insoluble.

Is iridium costly than gold?

Iridium, which is also used in spark plugs, has climbed to $6,000 an ounce, according to Johnson Matthey Plc data. That makes it more than three times more expensive than gold.

What is iridium used for today?

Iridium is the most corrosion-resistant material known. It is used in special alloys and forms an alloy with osmium, which is used for pen tips and compass bearings. It was used in making the standard metre bar, which is an alloy of 90% platinum and 10% iridium.

What are three uses for rubidium?

According to the New World Encyclopedia, rubidium doesn’t have many commercial uses but it is used in vapor turbines, in vacuum tubes, in photocells, in atomic clocks, in some types of glass, the production of superoxide by burning oxygen, and with potassium ions in several biological uses.

What is rhenium used for in everyday life?

Rhenium is used as an additive to tungsten- and molybdenum-based alloys to give useful properties. These alloys are used for oven filaments and x-ray machines. It is also used as an electrical contact material as it resists wear and withstands arc corrosion.

What is francium used for?

Francium has been used in the field of research, chemistry and also in the atomic structure. It is used for diagnostics for curing cancers. It is also used in many spectroscopic experiments. Francium is a highly radioactive metal, and since it exhibits a short half-life, it does not have more impact on the environment.

What is the chemical symbol of francium?

Francium is the chemical element with the chemical symbol Fr. This is the alkali metal element which is also listed as the radioactive metal element.

How is francium element made?

To make francium element, scientists can do bombarding thorium with protons or bombarding radium with neutrons. This article will cover the francium element uses in limited areas and also its discovery and chemical properties. You may also read:

Is francium a stable isotope?

Francium is the most unstable of the naturally occurring elements: its most stable isotope, Francium-223, has a half-life of only 22 minutes. Due to its instability and rarity, there are no commercial applications for Francium.
