Top 12 interesting facts about Dysprosium
Dysprosium was discovered in 1886 by Paul Emile Lecoq de Boisbaudran. Its name derives from the Greek word "dysprositos" which means "hard to get at".
Dysprosium's melting point is at 1412.0 C (1685.15 K, 2573.6 F) and its boiling point is at 2562.0 C (2835.15 K, 4643.6 F).
Dysprosium is a silvery rare-earth metal.
Dysprosium can be cut with a knife.
Dysprosium is never found freely in nature but in minerals (xenotime, fergusonite, gadolinite etc.)
Dysprosium reacts with air forming a layer of dysprosium oxide.
Dysprosium reacts slowly with cold water and quickly with hot water.
Dysprosium has seven stable isotopes; 164-dysprosium is the most abundant isotope of dysprosium.
Dysprosium is mainly produced in China.
Dysprosium has the highest magnetic strength (holmium has too), particularly at low temperatures.
Dysprosium is used in laser materials, commercial lightning, in nuclear reactors, in hard disks, in magnets, and other specialized uses.
Dysprosium powder when mixed with air can ignite.
