Dysprosium is used in data storage applications such as compact discs and hard discs. It is also used in medium source rare-earth lamps (MSRs) in the film industry. Dysprosium iodide is used these lamps to produce an intense white light. With vanadium, dysprosium is used in laser materials.

In this manner, is dysprosium poisonous or hazardous?

Hazards and risks associated with dysprosium: Dysprosium compounds are encountered rarely by most people. All dysprosium compounds should be regarded as highly toxic although initial evidence would appear to suggest the danger is limited. The metal dust presents a fire and explosion hazard.

Is dysprosium a metal?

An ancient city No, actually, dysprosium (Dy) is the 66th element in the periodic table and the ninth rare earth metal in the lanthanide series. The name dysprosium is derived from the Greek word "dysprositos," meaning hard to get at. In many ways this lesser known, somewhat mysterious element is true to its name.

Why is dysprosium expensive?

Low in toxicity, the metal has no known biological role. As a result, dysprosium and other heavy rare metals are often more expensive than light rare earths such as cerium and lanthanum.

What does dysprosium look like?

Characteristics: Dysprosium is a bright, soft, silvery-white, rare earth metal. It tarnishes slowly in air at room temperature and dissolves in both dilute and concentrated acids. Dysprosium also has a high thermal neutron absorption cross-section.


How is dysprosium used in cell phones?

Neodymium, terbium and dysprosium, for example, are three of the rare Earth metals: they give your phone the power to vibrate, so smartphones could be made without them – but you'd have to rely on your ringtone.

How is dysprosium extraction?

In common with many other lanthanides, dysprosium is found in the minerals monazite and bastnaesite. It can be extracted from these minerals by ion exchange and solvent extraction. It can also be prepared by the reduction of dysprosium trifluoride with calcium metal.

How is holmium used in everyday life?

Uses of Holmium
As a result of its special magnetic properties, holmium is used in alloys for the production of magnets and as a flux concentrator for high magnetic fields. Holmia (holmium oxide) is used as a yellow or red coloring for glass and cubic zirconia.

How is dysprosium made?

The metal was isolated by Georges Urbain, another French chemist, in 1906. Pure samples of dysprosium were first produced in the 1950s. Today, dysprosium is primarily obtained through an ion exchange process from monazite sand ((Ce, La, Th, Nd, Y)PO4), a material rich in rare earth elements.

Who invented dysprosium?

Paul-Émile Lecoq de Boisbaudran

How was Dysprosium discovered?

Dysprosium was discovered by Paul-Émile Lecoq de Boisbaudran, a French chemist, in 1886 as an impurity in erbia, the oxide of erbium. The metal was isolated by Georges Urbain, another French chemist, in 1906. When combined with vanadium and other rare earth elements, dysprosium is used as a laser material.

What is the electron configuration of dysprosium?

Xe 4f10 6s2

Is ytterbium toxic?

All compounds of ytterbium are treated as highly toxic, although studies appear to indicate that the danger is minimal. However, ytterbium compounds cause irritation to human skin and eyes, and some might be teratogenic. Metallic ytterbium dust can spontaneously combust, and the resulting fumes are hazardous.

What is dysprosium melting point?

1,412 °C

Where was thulium found?

Thulium was first isolated in 1879 as its oxide by Per Teodor Cleve at the University of Uppsala, Sweden. The discoveries of the many rare earth elements (aka lanthanoid) began with yttrium in 1794.

What is ytterbium used for?

Ytterbium metal has possible use in improving the grain refinement, strength, and other mechanical properties of stainless steel. One isotope is reported to have been used as a radiation source substitute for a portable X-ray machine where electricity is unavailable. Few other uses have been found.

What is terbium used for?

Terbium is used to dope calcium fluoride, calcium tungstate and strontium molybdate, all used in solid-state devices. It is also used in low-energy lightbulbs and mercury lamps.

What is the atomic mass unit of dysprosium?

162.5 u

Where is xenotime found?

Noteworthy Localities
Dipyramidal Xenotime crystals have come from the granite pegmatites of Aust-Agder and Vest-Agder, Norway, especially at the Evje-Iveland pegmatite field. Small prismatic crystals with pyramidal terminations were found in a Graphite mine in Amstall, near Mühldorf, Carinthia, Austria.
