In compounds of dysprosium (where known), the most common oxidation numbers of dysprosium are: 3. As the Investing News Network has previously discussed, deposits rich in heavy rare earths like dysprosium are less common than deposits rich in light rare earths. A higher recycling rate may reduce risk to supply. Dysprosium ingot, 99.9% trace rare earth metals basis CAS Number 7429-91-6. As a result Niobe fled to mount Sipylus and was turned to stone. Dysprosium is never found in nature as a free element, though it is found in various minerals, such as xenotime.Naturally occurring dysprosium is composed of seven isotopes, the most abundant of which is 164 Dy. Dysprosium was discovered by Paul-Émile Lecoq de Boisbaudran, a French chemist, in 1886 as an impurity in erbia, the oxide of erbium. Dysprosium and its compounds are among the most highly susceptible to magnetization of all substances and are used in special magnetic alloys. This has found applications in ships' sonar systems (underwater radar using soundwaves) and in all sorts of sensors and transducers. Dysprosium, like related elements, does not occur free in nature. Like other rare-earth or lanthanide elements, dysprosium occurs in a variety of minerals, including gadolinite, euxenite, xenotime, fergusonite, polycrase and blomstrandine. Dysprosium fluoride can be reduced into metal ingots by heating with calcium at … There seem to be a lot of dys- words around at the start of the 21st century, They have the Greek prefix for abnormal or bad - dyslexic, dyspepsia and dysfunctional spring to mind. MDL number MFCD00010982. Dysprosium, like many other lanthanides, is extracted from the minerals bastnaesite and monazite, as well as from some other minerals like fergusonite and xenotime [1].It can be obtained from these minerals through the process of solvent extraction and ion exchange [1].It can as well be manufactured by reducing dysprosium trifluoride using calcium metal [1]. As a result, it doesn't have as many applications as other elements that have been studied longer. Hydrides The term hydride is used to indicate compounds of the type M x H y and not necessarily to indicate that any compounds listed behave as hydrides chemically. These magnets are used in wind turbines and electrical vehicles, so demand for dysprosium is growing rapidly. The most important ores are monazite and bastnasite. Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure.The chemical symbol for Hydrogen is H.

It occurs in the Earth’s crust at an average concentration of 3 parts per million (ppm). An integrated supply risk index from 1 (very low risk) to 10 (very high risk). As a metal, dysprosium is reactive and yields easily oxides or salts of its triply oxidized form (Dy 3+ ion). Values for abundances are difficult to determine with certainty, so all values should be treated with some caution, especially so for the less common elements. Dysprosium can be found in a number of minerals. An element of the rare earth family that has the atomic symbol Dy, atomic number 66, and atomic weight 162.50.

It is difficult to separate from other rare earth elements. In 1879 Lecoq went on to extract pure samarium from the mineral samarskite whilst in 1886 he was the first person to identify dysprosium by separating its oxide from holmium oxide. The sum of the oxidation states within a compound or ion must equal the overall charge. Likewise the noble gases could easily be separated once cryogenics became feasible, thanks to the invention of Dewar's flask. Ask Question + 100.

The role of the element in humans, animals and plants. It’s a little too expensive to make widespread deployment practical, so researchers are on the hunt to find a cheaper, more plentiful substance to take its place. Like other heavier lanthanides, dysprosium has a lot of unpaired electrons, giving both the metal and its ions a high magnetic susceptibility.
