Description and Uses

There are not many uses for dysprosium. Scientists continue to experiment with it as apossible alloy metal (it has a high melting point) to be mixed with steel to make control rodsthat absorb neutrons in nuclear reactors. There are only a few commercial uses for dysprosium,such as a laser material and as a fluorescence activator for the phosphors used to produce thecolors in the older TV and computer cathode ray tubes (CRTs). When combined with steelor nickel as an alloy, it makes strong magnets.
