Boron-11 Uses

11B hardly absorbs neutrons, but it can be used as an additive for steel. This steel is used in the manufacture of reactors, which can greatly improve the high temperature resistance and corrosion resistance of the reactor without damaging the neutron physics in the reaction zone. situation.The uranium and plutonium borides (UB2 and PuB2) formed with 11B can significantly improve the thermal conductivity of their compounds. If 15N is used as an additive, the regeneration of plutonium in the presence of 11B can be significantly improved. It is worth noting that 11B is a potential thermonuclear reaction fuel. The energy generated by the reaction: 11B+p→34He is as high as 8.7 MeV, and this reaction is very high for 11B, which is very abundant in nature. meaningful. In addition, 11B can be used in the experimental study of proton radiation capture reaction in nuclear astrophysics.

10B and 11B are also used in the study of nuclear magnetic resonance technology. Both 10B and 11B have nuclear magnetic resonance activity, but 11B has a higher natural abundance and a smaller nuclear quadrupole moment, so it has higher sensitivity. In the NMR detection of boron-containing compounds, the application of 11B nucleus is the main application. 11BF3 gas can be used as raw material for ion implantation and doping process as well as room temperature curing agent, which can be used for packaging and fixing of radioactive hazardous waste. The enriched boron-11 mixture can be used in the CVD (capacitive voltage divider) industry to make parts with high wear resistance, oxidation resistance, corrosion resistance and certain electrical, optical and tribological properties。
