What is the usage of gadolinium?--2>

In the field of nuclear energy: in the atomic energy industry, the isotopes of europium and gadolinium are used as control rods and neutron absorbers for light water reactors and fast breeder reactors.

The use of gadolinium is the strong reaction of all elements to thermal neutrons. In addition to the control of atomic reactors, it can also absorb invisible neutrons with gadolinium and make them emit light, as a fluorescent agent for photosensitive X-ray film. use.

Gadolinium is also used in medical applications such as its water-soluble paramagnetic complexes to enhance nuclear magnetic resonance (NMR) imaging signals in the human body. Its sulfur oxides can be used as matrix grids for special brightness oscilloscope tubes and x-ray phosphor screens. Gadolinium in gadolinium gallium garnet is an ideal monolithic substrate for bubble memory memory. Can be used as solid-state magnetic refrigeration medium. It is used as an inhibitor of the chain reaction level in the control of nuclear power plants to ensure the safety of nuclear reactions. Used as an additive for samarium cobalt magnets to ensure performance does not change with temperature.

In addition, gadolinium oxide is used together with lanthanum to contribute to changes in the vitrified region and to improve the thermal stability of the glass. Gadolinium oxide can also be used to make capacitors and x-ray intensifying screens. In the world, efforts are being made to develop the application of gadolinium and its alloys in magnetic refrigeration, and breakthroughs have been made. A magnetic refrigerator using superconducting magnets, metal gadolinium or its alloys as the refrigeration medium at room temperature has come out.
