Boron carbide used in Nuclear Indusrty

Boron carbide is used to make control rods, control rods, accident rods, safety rods and shielding rods of nuclear reactors, to make boron carbide tiles, plates or neutron absorbers (made of high B10 content powder) for radiation protection, or to mix with cement to make shielding layer of nuclear reactors.

It is an important functional element next only to nuclear fuel elements. Characteristics: boron carbide can absorb a large number of neutrons without forming any radioisotopes, so it is an ideal neutron absorber in nuclear power plant, and it is also a core component of nuclear reactor. The neutron absorber mainly controls the rate of the nuclear reactor, but it is made into powder to increase the surface area.

Boron carbide is an important neutron absorbing material because of its high neutron absorption cross section, wide absorption energy spectrum, low price, abundant raw materials and no strong secondary radiation of λ – ray after absorbing neutrons.
