About Praseodymium Flange

 Praseodymium FlangePraseodymium flange standards include ASA/ANSI/ASME (USA), PN/DIN (European), BS10 (British/Australian), and JIS/KS (Japanese/Korean). Flange temperature and pressure tolerances are dependent on the rating. American Elements specializes in producing high purity uniform shaped Praseodymium Flanges. American Elements offers custom flanges with annealed or hard tempers and will meet most of the common Milspec or ASTM standards. Praseodymium flanges are circular with external ridges and varying threaded holes. In addition to standard alloys, American Elements also specializes in corrosion resistant alloys, high temperature applications, and custom shapes and forms, including custom hole drill locations and threading. American Elements also produces Praseodymium as rod, ingot, powder, pieces, disc, granules, wire, and in compound forms, such as oxide.

See more Praseodymium products. Praseodymium (atomic symbol: Pr, atomic number: 59) is a Block F, Group 3, Period 6 element with an atomic weight of 140.90765. Praseodymium Bohr Model The number of electrons in each of praseodymium's shells is 2, 8, 18, 21, 8, 2 and its electron configuration is [Xe]4f3 6s2. The praseodymium atom has a radius of 182 pm and a Van der Waals radius of 239 pm. Praseodymium resembles the typical trivalent rare earths, however, it will exhibit a +4 state when stabilized in a zirconia host. Elemental PraseodymiumUnlike other rare-earth metals, which show antiferromagnetic and / or ferromagnetic ordering at low temperatures, praseodymium is paramagnetic at any temperature above 1 K. Praseodymium is found in the minerals monazite and bastnasite. Praseodymium was discovered by Carl Auer von Welsbach in 1885. The origin of the element name comes from the Greek words prasios didymos, meaning green twin.
