American Elements' AE Bullion™ group mints certified high purity Lanthanum Bars 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 lanthanum price. Bars are manufactured and minted under written High Purity Metal Bars in Secure StorageSOPs (standard operating procedures) to assure quality and consistency by American Elements' AE Metals™ custom synthesis and refining group. Besides lanthanum bars, lanthanum coins and lanthanum 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 Lanthanum. 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 bar unit price to Lanthanum melt value ratio is maintained through state of the art mint and die systems and analytically certified blanks (planchet or flan) refined and pressed to exacting purity and weight. We also produce Lanthanum as rod, pellets, powder, pieces, disc, granules, and wire, as nanoparticles and in compound forms, such as oxide. Lanthanum Bars may be purchased in bulk or small quantity. Portfolios of different elemental metal bars or coins may also be structured and purchased from the AE Bullion™ group allowing for strategic risk allocation and indexing across a basket of metals.
