Holmium metal ingot - one troy ounce - .995 bullion
Discovered by the Swedish chemist Per Theodor Cleve and named after his hometown of Stockholm, holmium has the highest magnetic moment and magnetic permeability of any element, and thus can be used to manufacture the strongest magnetic fields. It also has high absorption capacity for thermal neutrons and is used as a burnable quenching agent in nuclear reactors. It is fairly stable in dry air at room temperature but will oxidize in moist air and at high temperatures, and will corrode when in contact with water. Holmium oxide has dramatic color spectra in different lighting conditions, from yellow to fiery orange-red. Its trivalent oxide has unique emission light lines that are useful in certain laser applications and as a colorant in cubic zirconia and glass. Worldwide annual production is about 10 tonnes (compared with about 3000 tonnes of gold).
Inscribed on our ingots are the chemical symbol (Ho), purity (99.5%), weight (one troy ounce), and a serial number (this number is unique and will vary). On the reverse is our logo. These ingots are lightly polished, similar to the one pictured. There can be tiny edge dings, faint surface scratches, and occasionally a shallow vertical groove on the edge of some of our holmium ingots, or other small imperfections which do not detract from the inherent value of this rare earth metal. They will oxidize, especially in humid and hot air. They will corrode when in contact with water. As always, weight and purity are guaranteed by Rare World Metals Mint. As we suggest with all of our metals please keep them intact in a cool, dry, safe place. Do not ingest and keep out of the reach of children.
Each ingot will be shipped with an assay certificate and every shipment will include our velvet logo bag.
