American Elements' AE Bullion™ group mints certified high purity Rhodium Bars from laboratory certified engineered materials with properties applicable to chemical vapor deposition (CVD) for thin film and laboratory standard impurity Rhodium Bars, Investment Grade Bullion, 999 Finelevels for short and long term physical possession and to allow for exposure and controlled risk to industrial demand fluctuations reflected in the global rhodium price.Besides rhodium bars, rhodium coins and rhodium 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 Rhodium. 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 Rhodium 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 Rhodium as rod, pellets, powder, pieces, disc, granules, and wire, as nanoparticles and in compound forms, such as oxide. Rhodium 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.

Rhodium (Rh) atomic and molecular weight, atomic number and elemental symbolRhodium (atomic symbol: Rh, atomic number: 45) is a Block D, Group 9, Period 5 element with an atomic weight of 102.90550. Rhodium Bohr ModelThe number of electrons in each of Rhodium's shells is [2, 8, 18, 16, 1] and its electron configuration is [Kr] 4d8 5s1. The rhodium atom has a radius of 134 pm and a Van der Waals radius of 195 pm. Rhodium was discovered and first isolated by William Wollaston in 1804. In its elemental form, rhodium has a silvery white metallic appearance. Elemental RhodiumRhodium is a member of the platinum group of metals. It has a higher melting point than platinum, but a lower density. Rhodium is found in ores mixed with other metals such as palladium, silver, platinum, and gold. Rhodium is primarily used as the catalyst in the three-way catalytic converters of automobiles; it is also highly valued in jewelry. The name Rhodium originates from the Greek word 'Rhodon,' which means rose.
