Boron carbide can absorb a large number of neutrons without forming any radioactive isotopes, so it is an ideal neutron absorber in nuclear power plants, and neutron absorbers mainly control the rate of nuclear weapons. Boron carbide is mainly made into a controllable rod shape in the nuclear reactor field, but sometimes it is made into a powder because of the increase in surface area.

During the Chernobyl nuclear accident in 1986, *** dropped nearly 2,000 tons of boron carbide and sand, which eventually stopped the chain reaction in the reactor. It can be used to manufacture gun nozzles in the military industry. Boron carbide, extremely hard and wear-resistant, does not react with acid and alkali, resistant to high/low temperature, high pressure, density ≥2.46g/cm3; microhardness ≥3500kgf/mm2, bending strength ≥400Mpa, melting point 2450℃. .Boron carbide is used to make control rods, regulating rods, accident rods, safety rods, and shielding rods for nuclear reactors, and to make boron carbide tiles, plates or neutron absorbers (made of high B10 content powder) for radiation protection, or the same Cement mixed to make nuclear reactor shielding layer is an important functional component second only to nuclear fuel components. Features: Boron carbide can absorb a large number of neutrons without forming any radioactive isotopes, so it is an ideal neutron absorber in nuclear power plants and is also a nuclear reactor core component. The neutron absorber is mainly to control the rate of nuclear weapons, but to increase the surface area, it is made into powder. Boron carbide has high neutron absorption cross-section, wide absorption energy spectrum, low price, rich source of raw materials, there is no strong secondary radiation of lambda ray after absorbing neutrons, so the waste is easy to handle, so boron carbide is an important neutron absorption material.
