Praseodymium 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.
Praseodymium is a Block F, Group 3, Period 6 element. The number of electrons in each of Praseodymium's shells is 2, 8, 18, 21, 8, 2 and its electronic configuration is [Xe]4f3 6s2. In its elemental form praseodymium's CAS number is 7440-10-0. The praseodymium atom has a radius of 182.pm and it's Van der Waals radius is is unknown. Praseodymium is somewhat toxic. Praseodymium resembles the typical trivalent rare earths, however, it will exhibit a +4 state when stabilized in a zirconia host. Praseodymium 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. The element is found in most all light rare earth derivatives. It is highly valued in glass and ceramic production as a bright yellow pigment because of its optimum reflectance at 560 nm. Much research is being done on its optical properties for use in amplification of telecommunication systems, including as a doping agent in fluoride fibers. The origin of the element name comes from the Greek words 'prasios didymos' meaning green twin. See Praseodymium 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.
PACKAGING SPECIFICATIONS FOR BULK & RESEARCH QUANTITIES
Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Shipping documentation includes a Certificate of Analysis and Material Safety Data Sheet (MSDS). Solutions are packaged in polypropylene, plastic or glass jars up to palletized 440 gallon liquid totes.
