American Elements' AE Bullion™ group mints certified high purity Praseodymium Coins from laboratory certified engineered materials with properties applicable to chemical vapor deposition (CVP) for thin film and laboratory standard impurity levels for short and long term physical possession and to allow for exposure and controlled risk to industrial demand fluctuations reflected in the global praseodymium price. Coins are manufactured and minted under written SOPs (standard operating procedures) to assure quality and consistency by American Elements' AE Metals™ custom synthesis and refining group. Besides praseodymium coins, praseodymium bars and praseodymium ingots may be purchased by funds, currency reserves, exchange-traded funds (ETFs), private investors, collectors and hobbyists to take direct physical title and possession of the metal with risk exposure from shortages or chemical/physical technology changes, such as in solar energy, and fuel cell developments, equivalent to movements in the industrial application price of Praseodymium. American Elements offers bonded short and long term warehouse inventory services for AE Bullion™ coins to investors, funds and collectors who do not wish to take physical custody of the metal or lack secure storage or warehouse capabilities. The lowest possible coin unit price to Praseodymium melt value ratio is maintained through state of the art mint and die systems and analytically certified rounds (planchet or flan) refined and pressed to exacting purity and weight. We also produce Praseodymium as rod, pellets, powder, pieces, disc, granules, and wire, as nanoparticles and in compound forms, such as oxide. Praseodymium Coins may be purchased in bulk or small quantity. Portfolios of different elemental metal coins or bars may also be structured and purchased from the AE Bullion™ group allowing for strategic risk allocation and indexing across a basket of metals.
Praseodymium is a Block F, Group 3, Period 6 element. The electronic configuration is [Xe]4f36s2. 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 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.
