What is dysprosium used for?
Dysprosium has a high thermal neutron absorption cross-section, meaning that it is very good at absorbing neutrons. Because of this, it is used to make the control rods that are put into nuclear reactors to absorb excess neutrons and stop fission reactions getting out of control.
Why is dysprosium expensive?
“Dysprosium, one of the most expensive heavy rare-earth elements, is used in neodymium sintered magnets to improve temperature resistance,” the company stated in a media release. “However, it is supplied from a single-country source, thus creating supply shortages and high prices as demand increases.
What’s the cost of dysprosium?
In 2020 the price of dysprosium oxide was 260 U.S. dollars per kilogram. There are 17 rare earth elements and although they are fairly abundant in the Earth’s crust, often they occur at sparse intervals are are less economically exploitable.
Is dysprosium paramagnetic or diamagnetic?
Magnetic Type of the elements
| Chromium | Antiferromagnetic | Sodium |
|---|---|---|
| Xenon | Diamagnetic | Dysprosium |
| Gold | Diamagnetic | Holmium |
| Mercury | Diamagnetic | Erbium |
| Thallium | Diamagnetic | Thulium |
What is the classification of dysprosium?
lanthanide
Dysprosium is a chemical element with symbol Dy and atomic number 66. Classified as a lanthanide, Dysprosium is a solid at room temperature.
What is dysprosium worth?
It is forecast that the price of dysprosium oxide be 440 U.S. dollars per kilogram in 2030. In 2020 the price of dysprosium oxide was 260 U.S. dollars per kilogram.

How common is dysprosium?
The abundance of dysprosium is 5.2 mg/kg in the Earth’s crust and 0.9 ng/L in sea water. Natural element 66 consists of a mixture of seven stable isotopes. The most abundant is Dy-154 (28%). Twenty-nine radioisotopes have been synthesized, plus there are at least 11 metastable isomers.
What is the use of dysprosium in transducers?
Similar to Tb, Dy is a component of the iron-based Terfenol-D, which is highly magnetic in room temperature, and hence is suitable for use in transducers, and wide-band mechanical resonators as well as highly precise liquid fuel injectors [74,75]. Dysprosium is also used in dosimeters applied to the measurement of ionizing radiations.
Which dysprosium compounds are soluble in water?
The majority of dysprosium compounds, with exceptions like Dy 2 (CO 3) 3 •4H 2 O and Dy 2 (C 2 O 4) 3 •10H 2 O are soluble in water.
What is the most common isotope of dysprosium?
Naturally occurring dysprosium is composed of the stable isotopes 156 Dy, 158 Dy, 160 Dy, 161 Dy, 162 Dy, 163 Dy, and 164 Dy, among which only 156 Dy decays with a t 1/2 of 1 × 10 18 years. 164 Dy and 162 Dy are the two most abundant isotopes accounting for 54% of the total weight of the samples [42].
How do you make dysprosium hydroxide?
Dysprosium was isolated by Paul Émile Lecoq de Boisbaudran in 1886, from holmium oxide, through a process based on dissolving dysprosium oxide in acid and then adding NH3 to increase the pH and hence precipitate its hydroxide.
