Is erbium toxic?
Erbium is slightly toxic if ingested, but erbium compounds are not toxic. Metallic erbium in dust form presents a fire and explosion hazard.
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 is erbium used in?
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 unique about erbium?
Unlike some other rare earth metals, erbium metal is fairly stable in air and does not oxidize as rapidly as some of the other rare-earth metals. Naturally occurring erbium is a mixture of six stable isotopes. In addition, nine radioactive isotopes of erbium are recognized.
Does the human body use erbium?
Health effects of erbium Erbium has no biological role even if it has been noted that it stimulates metabolism. It is difficult to determine the amount of erbium present in the human body. The levels are highest in bones, with smaller amounts being present in the liver and kidneys.
Why is erbium expensive?
Erbium is another illustrious member of the Rare Earth Gang. The exceedingly difficult task of separating it from the other rare earths is what makes it rare and expensive. The very few uses that have been found for this metal rest solely in its oxides or alloys.
What are 3 uses for erbium?
What is the atomic number of the element erbium?
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.
What kind of light is erbium used for?
Erbium is used in photographic filters to absorb infrared light. Erbium is also used in yttrium aluminum garnet (YAG) medical lasers for procedures involving skin resurfacing such as acne scars, mole removal tattoo removal and warts.
What happens when Erbium is dissolved in water?
Erbium. It slowly reacts with water and quickly dissolves in diluted acids, except hydrofluoric acid (HF) because of formation of the protective fluoride (ErF 3) layer on the surface of the metal. Erbium is a very strong paramagnet above approximately 85 K (−188 °C, or −307 °F). Between 85 K and 20 K…
What makes erbium a strong paramagnet in air?
Pure erbium is a silvery white metal that is relatively stable in air. It slowly reacts with water and quickly dissolves in diluted acids, except hydrofluoric acid (HF) because of formation of the protective fluoride (ErF 3) layer on the surface of the metal. Erbium is a very strong paramagnet above approximately 85 K (−188 °C, or −307 °F).
