Applications of Gadolinium Metal

Gadolinium is a silver-white metal with ductility. It has a melting point of 1313°C, a boiling point of 3266°C, and a density of 7.9004 g/cm. Thanks to its excellent physical and chemical properties, gadolinium metal enjoys a wide range of applications in medical, industrial, nuclear energy, and other fields. In this article, let's take a closer look at the applications of gadolinium metal.

Applications of Gadolinium Metal

Applications of Gadolinium Metal

  1. Application of Gadolinium in the Medical Field

In medical applications, the gadolinium-diethylenediamine pentaacetic acid (DTPA) complex can be used as an X-ray contrast agent barium as an adjustment agent for the intensity of MRI (magnetic resonance imaging diagnosis). In other words, the water around gadolinium is affected by the force of the gadolinium nucleus magnetic field, which shows that the nature of the water is different from that of unaffected water. The use of contrast images is conducive to the diagnosis of the disease.

  1. Application of Gadolinium in Industry

In the magnetic bubble memory device, gadolinium-potassium-garnet is used as the media material. Magnetic bubble memory is to add a magnetic field in the vertical direction of the substance to turn it into a cylindrical magnetic field. Strengthen the magnetic field, and the disappearance of the magnetic field will soon occur. The magnetic bubble memory device can store information, which is generally used for information collection.

Other uses of gadolinium are the same as terbium and dysprosium for optical fibers and optical discs. The magneto-optical recording is the use of light to replace the magnetized and unmagnetized parts of magnetic reading. It has the characteristics of high density and can be rewritten and recorded.

  1. Application of Gadolinium in Nuclear Energy

In the atomic energy industry, the large neutron absorption cross-section of the isotopes of europium and gadolinium can be used as control rods and neutron absorbers for light water reactors and fast breeder reactors.

Among all the elements, gadolinium reacts strongly to thermal neutrons. Taking advantage of this feature, gadolinium can also absorb invisible neutrons and make them emit light, which can be used as a fluorescent agent for photosensitive X-ray film.

Specific Uses of Gadolinium

  1. Its water-soluble paramagnetic complex can improve the human body's nuclear magnetic resonance (NMR) imaging signal in medical treatment. 
  2. Its sulfur oxide can be used as the matrix grid of a special brightness oscilloscope and X-ray phosphor screen.
  3. The gadolinium in the gadolinium gallium garnet is an ideal single substrate for bubble memory.
  4. When there is no Carnot cycle limitation, it can be used as a solid magnetic refrigeration medium. 
  5. It can be used as an inhibitor to control the chain reaction level of nuclear power plants to ensure the safety of nuclear reactions.
  6. It can also be used as an additive for samarium cobalt magnets to ensure that the performance does not change with temperature.
  7. In addition, the use of gadolinium oxide together with lanthanum contributes to changes in the vitrification zone and improves the thermal stability of the glass. Gadolinium oxide can also be used to make capacitors and X-ray intensifying screens. 
  8. The world is now working hard to develop the application of gadolinium and its alloys in magnetic refrigeration, and breakthroughs have been made. Magnetic refrigerators that use superconducting magnets, metal gadolinium, or their alloys as refrigeration media at room temperature have come out.
