Dysprosium is a silver-gray heavy metal that can be bent and stretched. There are two modifications of the rare earth metal: At 1384 ° C, α-dysprosium (hexagonal densest) changes to β-dysprosium (body-centered cubic). The metal is very ignoble and therefore very reactive. In the air it becomes coated with an oxide layer, in water it is slowly attacked with formation of hydroxides, in dilute acids it is dissolved to form salts with formation of hydrogen.
Dysprosium, atomic no. 66, symbol Dy, weight at 162.50, is most commonly used as in neodymium-iron-boron high strength permanent magnets. While it has one of the highest magnetic moments of any of the rare earths (10.6uB), this has not resulted in an ability to perform on its own as a practical alternative to neodymium compositions.
It is however now an essential additive in NdFeB production.
It is also used in special ceramic compositions based on BaTiO formulations.
Recent research has examined the use of dysprosium in dysprosium-iron-garnet (DyFeG) and silicon implanted with dysprosium and holmium to form donor centers.
