There are 13 isotopes of boron, the most common being boron 10 and boron 11. In the serious nuclear power plant explosion accident in the former Soviet Union, one of the most critical rescue actions is to drop a large amount of borax to the exploded reactor.

Boron-10 has strong radiation protection and neutron absorption functions, and has a wide range of applications in nuclear energy, national defense industry, medicine and science and technology fields. In the field of nuclear industry, boron-10 can be used as a neutron absorber or shielding material for reactors. With the development of nuclear power plants, the demand for boron-10 is increasing, and the quality requirements are also increasing.

In addition to being used in the nuclear industry, boron is also widely used in ceramics and glass metallurgy. Boron carbide has a relatively light structure and a high hardness. Therefore, boron carbide material can be used as the plug-in plate of bulletproof vest or bulletproof non-metallic armor on armored vehicles and armed helicopters.
