Boron carbide has been widely used in many fields such as nuclear power, aerospace, military and chemical industry, among which the application of boron carbide in nuclear field is the most valuable and promising.

In the chernobyl disaster of 1986, it took 2,000 tons of boron carbide to stop the chain reaction. Boron carbide has become the main raw material for neutron absorption materials due to its strong neutron absorption properties. Control rods, safety rods and shielding rods in nuclear reactor core components all depend on boron carbide's strong neutron absorption capacity.
