The dysprosium is a product that in room temperature is in solid state, has a silver color with pronounced and long lasting shine to the same as the chemical terbium presents stability against oxygen but is quite sensitive when it is at high temperatures, Dysprosium presents magnetism due to iron but when it is found at low temperatures its magnetic power is lost, an environment that changes when the temperature levels decrease significantly since it behaves with magnetic anisotropy, that is, it presents magnetism only in one region and in the opposite pole no. This element has an atomic number of 66, its atomic weight is 162.5 and is symbolized with Dy.
The name " dysprosium " is originally from the Greek " drysposito " whose meaning is difficult to obtain or difficult to obtain, and this name honors how complicated it was to extract this element from different minerals, in the years 1878 the French chemist Paul Emile Lecop Through the use of holimium and thulium oxides he was the first man to possess dysprosium in conjunction with other elements, this name is widely heard in the world of rare earths since he participated in the obtaining of various lanthanides, such as europium, samarium and gallium, in the year 1886 it was possible to completely separate the dysprosium oxides from the holmium oxides.
Despite his constant efforts, this Frenchman only obtained dysprosium in the form of oxide, it was not until 1950 in the hands of the Canadian scientist Frank Spedding that the element one hundred percent pure could be isolated without conjugation with oxygen, this it was achieved through the application of a technique in which an ionic exchange between metals was developed. Like its companions of the lanthanides, the main sources of dysprosium are different minerals known by the names of, euxenite, gadolinite, fergusonite and xenotime, being found in greater proportion in salts of monazite and bastnasite.. In an artificial way, it can be produced through the use of calcium ions, itself an increase in protons of the solution is made with the application of triofluoride and calcium.
