History
Dysprosium is a rare earth element that was first discovered in 1886 by French chemist Paul Émile Lecoq de Boisbaudran. He was working with the mineral gadolinite, which had been previously discovered in a mine in Ytterby, Sweden. Dysprosium was isolated as an impurity in yttrium oxide (Y2O3), which had been extracted from gadolinite. The name “dysprosium” comes from the Greek word “dysprositos,” meaning “hard to get at,” which reflects the difficulty of separating dysprosium from other rare earth elements.
Dysprosium’s properties were not fully characterized until the early 20th century. In 1906, Carl Auer von Welsbach separated dysprosium from other rare earth elements and discovered that it had strong emission lines in the yellow region of the spectrum. This made it useful for color television tubes and other applications that required a bright yellow color.
In the mid-20th century, dysprosium became important for its magnetic properties. It has one of the highest magnetic moments of any element and is used in the production of powerful permanent magnets, especially in applications such as wind turbines and electric vehicles. Today, China is the world’s largest producer of dysprosium, followed by the United States and Australia.
Occurrence and production
Dysprosium is found in various minerals including xenotime, fergusonite, gadolinite, euxenite, and blomstrandine. The element is typically extracted from monazite sand, a mineral that contains varying amounts of thorium and other rare earth elements. The largest deposits of monazite sands are found in Brazil, India, China, and Malaysia.
The production of dysprosium is a complex process that involves a series of chemical and metallurgical steps. The first step in the production process involves the extraction of rare earth elements from monazite sand using various methods such as solvent extraction, ion exchange, and precipitation. Once the rare earth elements are extracted, they are further separated using techniques such as solvent extraction and ion exchange. Dysprosium is then separated from the other rare earth elements using ion exchange or solvent extraction methods. The purified dysprosium is then converted into various forms such as oxides, metals, and alloys, which can be used in various industrial applications.
The production of dysprosium is typically carried out in countries that have significant reserves of rare earth minerals, such as China, which is the world’s largest producer of rare earth elements. Other major producers of dysprosium include Australia, the United States, and Russia. The production of dysprosium has become increasingly important in recent years due to its use in various high-tech applications, including electric vehicles, wind turbines, and other renewable energy technologies.
Properties
Dysprosium is a rare earth element that belongs to the lanthanide series of the periodic table.
Dysprosium is a soft, silvery-white metal that tarnishes quickly when exposed to air.
It has a relatively high melting point of 1407 ℃ and a boiling point of 2562 ℃.
Dysprosium is paramagnetic, which means that it is weakly attracted to magnetic fields.
It is also highly reactive with water and acids, and can ignite spontaneously in air.
Dysprosium has seven stable isotopes with atomic masses ranging from 156 to 164. The most stable of which is dysprosium-154 with a half-life of approximately 3 million years.
Applications
Dysprosium is a key component in the production of high-performance magnets used in wind turbines, hybrid vehicles, and other industrial applications.
Dysprosium is used in the production of specialized lighting, such as high-intensity discharge lamps, which are commonly used in streetlights and stadium lighting.
Dysprosium is used in the control rods of nuclear reactors to regulate the rate of fission reactions.
Dysprosium is used in the production of magneto-optical disks, which are used for data storage in some computer systems.
Dysprosium is used in magnetic resonance imaging (MRI) as a contrast agent to enhance the visibility of certain tissues and organs.
