Dysprosium (Dy)

Dysprosium (Dy)

Dysprosium was discovered in 1886, but neither the metal nor its oxide was available until 1950. It occurs naturally with other rare earth metals in a variety of minerals.

This element has a bright metallic luster and is relatively stable at room temperature. Dysprosium can be cut with a knife and machined without sparking if not overheated. Minute impurities can significantly affect its physical properties.

Not many applications exist for dysprosium, but it may have metallurgical uses in nuclear control applications or for special stainless-steel alloys. When combined with other rare earth metals, it's used in laser materials.
