How did dysprosium get its name?
Dysprosium was discovered in 1886 by French chemist Paul Émile Lecoq de Boisbaudran when he separated dysprosium oxide from holmium oxide. Fittingly he named the element dysprosium, from the Greek ‘dysprositos’ meaning ‘hard to obtain.
What are 3 uses for dysprosium?
Dysprosium is used in control rods for nuclear reactors because of its relatively high neutron-absorption cross section; its compounds have been used for making laser materials and phosphor activators, and in metal halide lamps.
Why is the element dysprosium so important?
Dysprosium has a high thermal neutron absorption cross-section, meaning that it is very good at absorbing neutrons. Because of this, it is used to make the control rods that are put into nuclear reactors to absorb excess neutrons and stop fission reactions getting out of control.
What are 3 uses for erbium?
Uses of Erbium Erbium isotopes are good neutron absorbers and are used in nuclear reactor control rods. 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.
What reacts with dysprosium?
Dysprosium is a lustrous, very soft, silvery metal. It is stable in air at room temperature even if it is slowly oxydized by oxygen. It reacts with cold water and rapidly dissolves in acids.
What is dysprosium family name?
rare earth family
Please visit the Dysprosium element page for information specific to the chemical element of the periodic table. Dysprosium atom is a lanthanoid atom and a f-block element atom. An element of the rare earth family that has the atomic symbol Dy, atomic number 66, and atomic weight 162.50.
What is dysprosium natural state?
It is a rare-earth element with a metallic silver luster. 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 164Dy.

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 family does dysprosium come from?
Dysprosium. An element of the rare earth family that has the atomic symbol Dy, atomic number 66, and atomic weight 162.50. Dysprosium is a silvery metal used primarily in the form of various salts.
What is dysprosium used for?
Dysprosium is used in control rods for nuclear reactors because of its relatively high neutron-absorption cross section; its compounds have been used for making laser materials and phosphor activators, and in metal halide lamps.
Where is dysprosium found?
Dysprosium is never found in nature as the free element. Dysprosium is found in the ores monazite sand [(Ce, La, etc.)PO4] and bastn°site [(Ce, La, etc.)(CO3)F], ores containing small amounts of all the rare earth metals.
