What is erbium used for?
Uses of Erbium The oxide erbia is used as a pink coloring agent in glazes and glasses. Erbium is used in alloys especially with vanadium to decrease the hardness of metals. It is also used in amplifiers and lasers. Erbium is used in photographic filters to absorb infrared light.
What is europium used for?
Europium is excellent at absorbing neutrons, making it valuable in control rods for nuclear reactors. Europium-doped plastic has been used as a laser material. It is also used in making thin super-conducting alloys.

Is erbium natural or synthetic?
Erbium is a chemical element with the symbol Er and atomic number 68. A silvery-white solid metal when artificially isolated, natural erbium is always found in chemical combination with other elements.
Why is erbium so expensive?
Their location makes them remarkably insensitive to the world outside – which is why the colours are so consistent from compound to compound. But what Bunsen could not know, was that there were spectroscopic bands in the infrared part of the spectrum and it is these that are what makes erbium so valuable to us today.
What group is osmium?
platinum metals
osmium (Os), chemical element, one of the platinum metals of Groups 8–10 (VIIIb), Periods 5 and 6, of the periodic table and the densest naturally occurring element. A gray-white metal, osmium is very hard, brittle, and difficult to work, even at high temperatures.
What is the costliest element in the world?
As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium. It is followed by caesium, iridium and palladium by mass and iridium, gold and platinum by volume. Carbon in the form of diamond can be more expensive than rhodium….Prices of chemical elements.
