Praseodymium Carbide is
available in numerous forms and custom shapes including Ingot, foil, rod, plate and sputtering target. High purity forms also include Carbide powder, submicron powder and nanoscale, single crystal or polycrystalline forms. Arsenic Carbide is generally immediately available in most volumes.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.
Like diamond, a pure carbon compound, Carbide compounds tend to be extremely hard, refractory and resistant to wear, corrosion and heat, making them excellent candidates for coatings for drills and other tools. They often have other valuable properties in combination with toughness, such as electrical conductivity, low thermal expansion and abrasiveness.
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.
