In nature, the natural isotopes of boron are boron-10 and boron-11, of which the natural abundance of boron-10 is less than 20%. High-abundance boron-10 series products must be prepared manually.
Boron-10 has an efficient neutron absorption capacity, its ability to capture thermal neutrons is about 80,000 times that of boron-11, and it is a neutron absorber in the field of nuclear technology.
Different boron-10 series products are used in specific applications. Common ones are boron-10 acid, boron-10 powder, boron carbide-10, boron nitride-10, boron-10 zirconium and so on.
Boron-10 acid is one of the boron-10 homologues, and boron-10 powder and other boron-10 homologues are usually produced from boron-10 acid as the starting material. Boron-10 acid can not only be used directly as a neutron absorber, but also a raw material for the manufacture of other boron-10 series neutron absorbers, so it is known as the core material of boron-10 series neutron absorbers.
High-abundance boron-10 series neutron absorbers have made great contributions to the field of nuclear technology:
In the nuclear industry, it can ensure that the start-up, shutdown and power output of the nuclear reactor reach a high level of control, ensure that the nuclear reactor cooling system has an efficient neutron shielding effect, and ensure that the storage, transportation and disposal of nuclear waste are leak-free. the safe;
In national defense construction, it is the decisive material for the miniaturization of nuclear reactors and the lightening of nuclear equipment;
In nuclear medicine, as a highly effective agent for targeted therapy of cancer, it is considered to be the terminator of cancer cells.
