Dysprosium metal is a silvery white rare earth metal with a melting point of 1412°C, a boiling point of 2562°C, a density of 8.55g/cm3, low hardness, and superconductivity near absolute zero. Dysprosium is quite stable in the air, active at high temperatures, and easily oxidized by air and water to form dysprosium oxide. The abundance of dysprosium in the earth’s crust is 6ppm, and it usually coexists with erbium, holmium and other rare earth elements in minerals such as monazite sand.

Rare earth magnets: Dysprosium metal is an important magnetic material, especially useful for making powerful permanent magnets. Dysprosium is used along with other rare earth elements to make high performance magnets. Dysprosium magnets have a high magnetic energy product and high magnetic toughness, and are therefore used in a wide range of applications such as electric motors and magnetic sensors.
Magnetic refrigeration technology: The magnetic entropy effect of dysprosium makes it a key component in magnetic refrigeration technology. In magnetic refrigeration, dysprosium can realize refrigeration effect through magnetic entropy change. This technology can be used in cryogenic refrigeration, medical imaging equipment and magnetic resonance imaging (MRI) systems.
Lighting and display technologies: Dysprosium metal compounds have luminescent properties and are used in the manufacture of phosphors for fluorescent lamps, light-emitting diodes and displays. The use of dysprosium in fluorescent display technology helps to improve color stability and display performance.
Nuclear magnetic resonance (NMR): Dysprosium metal is used as a probe in nuclear magnetic resonance (NMR) studies, especially in solid-state NMR experiments. Dysprosium’s special magnetic properties make it unique in this regard.
Metal alloys: Dysprosium metal can be alloyed with iron and other rare earth elements to produce a range of metal alloys for specific industrial applications. These alloys exhibit excellent performance in environments such as high temperatures and high magnetic fields.
1. Atomic absorption spectroscopy (AAS): This is a common quantitative analysis method that uses absorption spectra at specific wavelengths to determine the concentration of dysprosium in a sample. The sample is dissolved or converted into a gaseous form, and then atomized to an atomic state. Subsequently, a light source of a specific wavelength is used to illuminate the sample, and the intensity of the light absorbed by the sample is measured to infer the concentration of dysprosium.
2. Inductively coupled plasma optical emission spectrometry (ICP-OES): This is a highly sensitive analysis method that can detect multiple elements at the same time. The sample is ionized and sprayed into a high-temperature plasma, which excites radiation spectra unique to various elements. The detection instrument analyzes these spectra to identify and determine the content of dysprosium based on their intensity and wavelength.
3. Mass spectrometry (MS): Mass spectrometry detects elements by accurately measuring the molecular mass of ions in a sample. In dysprosium analysis, a mass spectrometer can be used to measure the mass of dysprosium ions, and the presence and concentration of dysprosium can be determined by analyzing the mass and relative abundance of its ions.
4. Fluorescence spectroscopy: This method uses the fluorescence produced by dysprosium under specific conditions for detection. When the sample is exposed to an excitation light source, the dysprosium element absorbs energy and emits fluorescence of a specific wavelength. The presence and concentration of dysprosium are determined by measuring the intensity and characteristics of the fluorescence.
5. X-ray diffraction (XRD): Although it does not directly measure the content of dysprosium, X-ray diffraction can be used to analyze the characteristics of the crystal structure in the sample. This method can help confirm the relative content and structure of rare earth compounds in the sample, thereby indirectly determining the presence of dysprosium.
