Boron carbide has great application potential in many fields, among which the application of boron carbide in nuclear field is the most valuable and promising. Boron carbide can be used as neutron absorption material for control rods and shielding materials in reactors.

These unusual properties of boron carbide are closely related to its unique crystal structure and chemical bonds. The atomic structure of boron carbide has been extensively studied. Its main structural units are the icosahedron composed of twelve atoms and a three-atom chain connected to the icosahedron.

Boron carbide has been widely used in many fields, such as nuclear power, aerospace, military and chemical industry, etc. However, the crystal structure of boron carbide is still controversial. At present, it is widely believed that there are many possible isomers of boron carbide. The essential relationship between the complex crystal structure of boron carbide and its unique properties needs further study.
