Erbium metal ingot - one troy ounce - .995 bullion
Discovered by the Swedish chemist, Carl Gustaf Mosander in 1843, erbium is one of the 17 rare earth elements. It and the other rare earth elements sit atop the British Geological Survey's Risk List. It has many industrial uses including in nuclear reactor control rods, as an alloying agent in metallurgy, in fiber optics, infrared lasers, and as a colorant (its oxide is a rose pink color) for glass, porcelain and jewelry.
Inscribed on our ingots are the chemical symbol (Er), 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, scratches, and other tiny imperfections which do not detract from the inherent value of this rare earth metal. Though we've chosen certain rare earth metals that have lesser problems with oxidation, our erbium ingots will still oxidize and they have a darker cast compared with our other metals as a result. They are best stored in a cool, dry place. As always, weight and purity are guaranteed by Rare World Metals Mint. If erbium is ingested it could be toxic, though generally is considered safe when handled appropriately. It's fine turnings or powder form can ignite or even explode in air. As we suggest with all of our metals please keep in a safe place, do not ingest, and keep out of the reach of children.
