Dysprosium (Dy)

Regular price $68.95 Sale

Dysprosium metal ingot - one troy ounce - .995 bullion

 

 

Discovered in Paris in 1886 by Paul Emile Lecoq de Boisbaudran and named for the Greek translation of dysprositos which means "hard to get", techniques to purify dysprosium were not refined until the 1950s after ion exchange techniques were developed. Dysprosium along with holmium (another of our rare earth metals) have the highest magnetic strength of all the elements. About 100 tonnes of dysprosium (compared with over 2500 tonnes of gold) is produced worldwide annually with 99% of this coming from China. It has many industrial uses, many of which are are in emerging clean energy technologies. The U.S. Department of Energy had previously predicted a shortage of dysprosium as early as 2015. It along with the other rare earth metals sit atop the British Geologic Survey's Risk List. 
 
 
Inscribed on our ingots are the chemical symbol (Dy), 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 small edge dings, scratches and other small imperfections which do not detract from the inherent value of this rare earth metal. Though oxidation is not typically a big problem with dysprosium metal as it can be with other rare earth metals, it will still oxidize and these ingots have a little darker cast compared with our non-rare earth 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.  The solid ingot form of dysprosium generally is considered safe when handled appropriately. It's fine turnings or powder form can ignite and explode.  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.

   

Each ingot will be shipped with an assay certificate and with our velvet logo bag for storage.
