Boron Carbide Ceramics for Neutron Absorption in Nuclear Reactors

Neutron Absorbing Boron Carbide Ceramics

Product introduction

Boron carbide (B•Cl has excellent neutron absorption ability,with a high neutron capture c『"Oss-sectional area and a wide capture energy spectrum. The thermal cross section of 108 is as high as 3750 bar (a bar unit for nuclear reactions, 1.0 ’ 10-24cm句,second.Only to a few elements such as gadolinium Gd, samarium Sm,cadmium Cd, etc. Meanwhile, compared to pure elements B and Gd,B4C has a lower cost, does not produce radioactive isotopes, has lower secondary radiation energ弘and is easier to dispose of as waste; Moreover, it is corrosion-resistant and has good thermal stability, making it a widely accepted fast neutron absorbing material internationally. At present, it is widely used as a shielding plate and neutron absorption core block for nuclear industry atomic energy reactors.
