Dysprosium Hydride is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered. Hydride compounds are used often used as portable sources of hydrogen gas.American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia)and follows applicable ASTM testing standards.Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
Dysprosium is a Block F, Group 3, Period 6 element. The number of electrons in each of Dysprosium's shells is 2, 8, 18, 28, 8, 2 and its electronic configuration is [Xe] 4f10 6s2. In its elemental form dysprosium's CAS number is 7429-91-6. The dysprosium atom has a radius of 175.2.pm and it's Van der Waals radius is unknown. Dysprosium is moderately toxic. Dysprosium is most commonly used in neodymium-iron-boron high strength permanent magnets. Dysprosium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. While it has one of the highest magnetic moments of any of the rare earths (10.6µB), 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 (DyIG) and silicon implanted with dysprosium and holmium to form donor centers. Dysprosium is added to various advanced optical formulations due to the fact that it emits in the 470-500 and 570-600 nm wavelengths. Dysprosium was first discovered by Paul Emile Lecoq de Boisbaudran in 1886. The element name originates from the Greek word 'dysprositos' meaning hard to get at. See Dysprosium research below.
Hydrogen is a Block S, Group 1, Period 1 element. The electronic configuration is 1s1. In its elemental form hydrogen's CAS number is 1333-74-0. The hydrogen atom has a radius of 37.3.pm and it's Van der Waals radius is 120.pm. Hydrogen is highly flammable. Hydrogen was discovered by Sir Henry Cavendish in 1766.
