Product introduction

       Boron-10 acid is a solid state. Due to its strong absorption of slow neutrons and gamma rays, it can also release alpha rays and 7Li particles; the boron 10 isotope product is a neutron absorber or shielding material for nuclear reactors. Yixin Environmental Protection's unique technical process has broken through high-abundance products with abundance ≥95% and purity ≥99.95%. Yixin's environmentally friendly high abundance and high purity (abundance ≥95%, purity ≥99.95%) boric-10 acid products have reached the domestic leading level.       In order to meet the rapid increase in market demand, Yixin Environmental will expand the production of items in 2020; after the completion of the items, the production capacity will exceed 40 tons/year of high-abundance boric-10 acid products.

Application field

Nuclear Industry

       At present, traditional fossil energy sources such as oil and coal are increasingly scarce, and the research and development of new alternative energy sources is imminent. Nuclear energy is a sustainable energy source. As an economic and effective measure to alleviate the world energy crisis, the application of nuclear energy is particularly important to the development of my country's energy industry. Among them, nuclear power plants have an extremely important position. There are hundreds of nuclear power plants under construction and planned to be built all over the world. In the 13th Five-Year Plan, the country plans to build 10-12 new nuclear power plants every year; each unit of the newly built nuclear power plant will directly consume 100 tons of boron-10 acid, and after completion, each nuclear power plant will consume 13 tons of boron-10 acid annually. At present, with the further improvement of nuclear power safety requirements, the second and third generation nuclear power technologies in nuclear power plants have become the mainstream. For the sake of safety and economy, in the second and third generation nuclear power technology R&D and design processes, high-abundance boron-10 acid is used to replace the natural abundance of boron, which is compared with the natural abundance of boron. , The high abundance of boron-10 isotope can make the nuclear reaction operation control reach a higher level. With the vigorous development of nuclear power plants, the demand for boron-10 acid is increasing and the quality requirements are getting higher and higher. However, because the domestic boron-10 acid has not been industrialized, and the import price is very expensive, the refined technology of boron isotope separation developed by the company is undoubtedly of extremely important significance.

Defense industry

       Boron-10 isotope has good neutron absorption properties and can be used as neutron absorber and radiation shielding material. Military protection materials mixed with boron-10 isotope can be used to make military clothing for neutron bomb protection. Many modern weapons have been driven by nuclear power, such as nuclear submarines and nuclear-powered aircraft carriers. The nuclear reaction process requires boric acid to control. If boric acid enriched with boron-10 isotope is used, the space used for storing boric acid can be reduced and the weight can be reduced. Load more weapons, ammunition and materials to enhance its combat capabilities; alloy steel made by incorporating boron-10 isotope into metal materials through smelting technology has high hardness and light weight, which can greatly reduce the load on ships and improve the ship’s performance. Combat capability. However, due to the constraints of the raw material boron-10 acid, its development speed is slow, so its prospects are very broad in the field of national defense applications.

Medical treatment

       Boron-10 acid plays an important role in cancer treatment. In medicine, there is a new radiotherapy method called Boron Neutron Capture Cancer (BNCT). This method has a better therapeutic effect on melanoma and glioma, and the treatment cost is relatively low. This drug is selective for cancer cells. The concentration of the drug in cancer cells is several times higher than that in normal cells and blood. Neutrons mainly react with the target nuclides (such as boron-10 isotope) in BNCT drugs to produce The secondary radiation a-rays and recoil particles Li, which kill cancer cells, have strong targeting and high intensity. Due to the low drug concentration in normal cells and blood, the damage caused by neutron irradiation is relatively small and easy to repair. Therefore, the BNCT method has fewer side effects than conventional radiotherapy; at the same time, boron-10 acid is easier to enter human tissues and has less harm to the human body, so the clinical application effect is very good. In terms of cancer treatment, there are currently 24 domestic targeting machines, and the number will increase year by year. Each targeting machine consumes 400 kilograms of boron-10 acid per year, so the development prospect of boron-10 acid in the medical industry is very impressive.

       In nuclear medicine, boron-10 acid is used in boron neutron capture therapy (BORON NEUTRON CAPTURE THERAPY, BNCT) technology to prepare boron-containing targeted high-efficiency drugs, which are widely used in tumor treatment. Under neutron beam irradiation, the 17LI and α particles produced by the ionization of boron-10 acid are enough to kill tumor cells, and they do little harm to normal tissues and produce almost no side effects.
