Dysprosium Ingot

MATERIAL OVERVIEW

Characteristics: Dysprosium is a rare earth element and member of the lanthanide family with a metallic silver luster. Dysprosium is never found in nature as a free element, though it is found in various minerals, such as xenotime. It is A noncorrosive metal and does not react with moist air to form hydroxide. Reacts slowly with water and halogen gases, soluble in dilute acids. High cross-section for thermal neutrons. Low toxicity. soft enough to be cut with a knife, and can be machined without sparking if overheating can be avoided. Dysprosium (and holmium) have the highest magnetic strengths of the elements, specifically if at low temperatures.

Derivation: Dysprosium is obtained primarily from monazite sand, a mixture of various phosphates. The metal is acquired as a by-product in the commercial removal of yttrium. To isolate dysprosium, the majority of the unwanted metals are removed magnetically or by flotation process. Dysprosium is then separated from other rare earth metals by an ion exchange displacement technique.

Dysprosium is used for its high thermal neutron absorption cross-section in making control rods in nuclear reactors, for its high magnetic susceptibility in data storage applications . In addition, Dysprosium it is used along with vanadium and other elements, in making laser materials and for commercial lighting.

Hazards: Soluble dysprosium salts, such as dysprosium chloride and dysprosium nitrate, are mildly toxic when ingested. Like many powders, dysprosium powder may present an explosion hazard when mixed with air and when an ignition source is present. Thin foils of the substance can also be ignited by sparks or by static electricity. Dysprosium fires typically cannot be put out by water.
