Dysprosium is named from the Greek dysprositos, hard to get at and was discovered in 1886. Dysprosium is found along with the other rare-earth minerals principally in monazite and bastnasite. The metal is isolated using ion exchange and solvent extraction methods. Dysprosium, like the other rare-earth metals, has a bright silver luster and is malleable and ductile. Dysprosium is not used commercially, but its thermal absorbtion cross section and high melting point may make it useful in nuclear control applications for alloying with special stainless steels.
