Gadolinium metal has a wide range of applications in various fields such as medicine, industry, and nuclear energy.
In the medical field, gadolinium metal is mainly used as a contrast agent for magnetic resonance imaging (MRI).
In the industrial field, gadolinium sulfur oxides can be used as matrix grids for special brightness oscilloscopes and X-ray fluorescence screens; Gadolinium in gadolinium gallium garnet is an ideal single substrate for magnetic bubble memory storage;
Gadolinium metal can also be used in microwave technology, fluorescent powders for color televisions, and in the preparation of special alloys.
In addition, gadolinium metal can also be used in magnetic refrigeration technology. By magnetizing gadolinium salts, ultra-low temperatures close to absolute zero can be obtained. Without Camot cycle limitations, it can be used as a solid-state magnetic refrigeration medium.
