Boron carbide material has high neutron absorption capacity, high neutron capture cross section, fast absorption spectrum, no secondary radiation pollution, and corrosion resistance, wear resistance, good thermal stability, is a good control rod material.

Boron carbide is widely used in nuclear reactors: boron carbide is used in the periphery of the reactor, and graphite composite, the preparation of boron carbon brick, can prevent the leakage of radioactive substances; Can be used as reactor shielding material, used for the second layer of reactor protection, absorption of radioactive substances; Can control reactor reaction speed, used as reactor control rod.
