Boron carbide, also known as black diamond, is an organic substance with a molecular formula of B₄C, usually gray-black fine powder. It is one of the three hardest materials known (the other two are diamond and cubic boron nitride). It is used in tank armor, bulletproof vests and many industrial applications. Boron carbide can absorb a large number of neutrons without forming any radioisotopes, so it is an ideal neutron absorber in nuclear power plants, and neutron absorbers mainly control the rate of nuclear fission. 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.
(1) The field of national defense. Boron carbide ceramics have been used in bullet-proof since the 1960s. Compared with other materials, it has the characteristics of easy portability and high hardness. It plays a huge role in the lightweight armor of armed helicopters and the bulletproof armor of aircraft. The British used it as a raw material to make armor that can defend against armor-piercing projectiles.
(2) In terms of chemical raw materials. In order to increase the wear resistance and strength of alloy materials, boron carbide is used as a boronizing agent for alloys, which can be boronized on the metal surface to generate a thin layer of iron boride; it can also be used as a boron source to generate boride powder by reduction and method Such as TiB2, ZrB2, CrB2, or "B4C method" to prepare boron halide, hydrogen boride, etc.
(3) Wear-resistant field. Various industrial nozzles such as desander nozzles for rust removal and nozzles used for cutting with high-pressure water guns have the shadow of boron carbide ceramics. They are often the first choice for factories because of their long service life under extreme conditions and high cost performance. . It is also often used as a research body in the chemical analysis process, because it can effectively avoid the pollution caused by abrasive loss during the grinding process. As a substitute for diamond abrasives, boron carbide can significantly reduce costs in the processing of various hard metals and jade glass.
(4) Nuclear energy. Because of its excellent neutron absorption capacity, boron carbide is often used in neutron absorption material control rods, safety rods and other components to control the rate of nuclear fission and protect human body safety.
(5) Aviation. In the rocket power system, the rocket engine, boron carbide plays an important role as an important raw material for the shaft tip of the flow transmitter that transports liquid fuel; in the navigation system of the aircraft, the gyroscope is indispensable An important component, boron carbide as an additive material for the gyroscope can effectively increase its life
