Properties and applications of boron carbide
From April the French government will reduce fuel taxes slightly to ease the burden on consumers.
Warned of possible energy shortages in France by the end of the year and called on the French to conserve electricity and gas from now on, saying that if nothing was done, The energy situation will be tough this winter. Some experts say that there are two main reasons for France's energy crisis: first, the conflict between Russia and Ukraine affected the gas market and caused supply tension; The second is a safety review of France's newest nuclear power plant, which may lead to a reduction in output this year. In order to alleviate the energy crisis, the whole French society needs to be mobilized, whether it is the industrial sector, the tertiary sector or every French citizen. Now it is urgent. Rising fuel prices may also have an impact on shipments of the Boron Carbide B4C powder,Overview of Boron Carbide B4C powder,Application of boron carbide B4C powder,Boron carbide B4C powder price,Boron Carbide B4C Powder Supplier.
Overview of Boron Carbide B4C powder
Boron carbide (B4C) is also known as black diamond. It is gray-black and is a very hard man-made material: the Mohs hardness is 9.3, and the microhardness is 5500~6700kg/mm2, second only to diamond and cubic boron nitride.
The structure of boron carbide is hexagonal. The density of boron carbide is 2.52g/cm3. The melting point of boron carbide is 2450℃, and it decomposes and volatilizes rapidly when the temperature is higher than 2800℃.
Boron carbide B4C powder properties
Boron carbide is insoluble in water and organic solvents, has strong chemical stability, is resistant to acid and alkali corrosion, and hardly reacts with all acid and alkali solutions. The thermal neutron capture cross section of boron carbide is large and the neutron absorption ability is strong, so it is called a neutron absorber and a semiconductor.
Application of boron carbide B4C powder
Due to its attractive combination of properties, it is a suitable material for many high-performance applications.
The excellent hardness of boron carbide makes it a suitable abrasive for grinding, polishing and water jet cutting of metals and ceramics. It is suitable for grinding, polishing, drilling and other processing of various carbide tools, molds, parts, components and gemstones. Boron carbide can be made into abrasive paste and polishing paste with appropriate amount of oil or water as lubricant.
Control nuclear fission
Boron carbide can absorb a large number of neutrons without forming any radioactive isotopes. It is an ideal neutron absorber in nuclear power plants. Neutron absorbers mainly control the rate of nuclear fission. Boron carbide is mainly used in nuclear reactors as controllable rods, but is sometimes powdered due to increased surface area.
During the Chernobyl nuclear accident in 1986, Russia dropped nearly 2,000 tons of boron carbide and sand, which ultimately stopped a chain reaction within the reactor.
Because boron carbide has long been used as a rough grinding material. Due to its high melting point, it is not easy to cast into artificial products, but it can be processed into simple shapes by melting powder at high temperature. For grinding, grinding, drilling and polishing of hard materials such as carbide and gemstones.
Boron carbide can also be used as ceramic coatings for warships and helicopters. It is lightweight and has the ability to resist penetration of armor-piercing projectiles through thermocompression coatings, forming a complete defensive layer.
In the arms industry, it can be used to make gun barrels. Boron carbide, extremely hard and wear-resistant, does not react with acid and alkali, high and low temperature resistance, high pressure resistance, density ≥2.46g/cm3; microhardness ≥3500kgf/mm2, flexural strength ≥400MPa, melting point 2450℃.
Since boron carbide nozzles have the above-mentioned characteristics of wear resistance and high hardness, boron carbide sandblasting nozzles will gradually replace known cemented carbide/tungsten steel and silicon carbide, silicon nitride, alumina, zirconia and other sandblasting nozzles.
Boron carbide is also used in the manufacture of metal borides, smelting sodium boron, boron alloys and special welding.
