What is Boron Carbide B4C?
U.S. natural gas futures rose about 5 percent to a near nine-week high as global energy prices surged on concerns over a pricing plan for energy exports, keeping U.S. LNG export demand near record highs. U.S. natural gas prices have risen despite forecasts of mild weather and lower-than-expected demand, which will allow utilities to fill up storage facilities next week. On Wednesday, Germany launched an emergency plan to manage gas supplies in Europe's largest economy. If natural gas supplies are interrupted or stopped, the German government could take unprecedented steps to limit electricity supply.
Affected by the increase in the price of natural gas, the price of the boron carbide powder will also increase.
What is Boron Carbide B4C?
Boron carbide, also known as black diamond, is an inorganic substance with the chemical formula B4C. Hard black lustrous crystal.
It has a Mohs hardness of about 9.5, making it one of the three hardest materials known (after diamond and cubic boron nitride). Less fragile than most pottery. Used in tank armor, bullet-proof vests and many industrial applications. Relative density (D204)2.508 to 2.512. Melting point is 2350 ℃. The boiling point of 3500 ℃.
Boron carbide does not react with acid and alkali solution, has high chemical potential, does not react with acid and alkali solution, has high chemical potential, neutron absorption, wear resistance and semiconductor conductivity. It is one of the most stable to acids and is stable in all concentrated or dilute acid or alkaline solutions. Boron carbide is basically stable under 800℃ in the air environment, due to the higher temperature of the oxidation of boron oxide in the gas phase loss, resulting in its instability, oxidation to form carbon dioxide and boron trioxide.
It was discovered in the 19th century as a by-product of research on metal borides and was not studied scientifically until the 1930s. Boron carbide can be prepared by reducing boron trioxide with carbon in an electric furnace.
Because of its low density, high strength, high temperature stability and good chemical stability. In wear resistant materials, ceramic reinforcement, especially in light armor, reactor neutron absorbent applications. In addition, compared with diamond and cubic boron nitride, boron carbide is easy to manufacture, low cost, so it is more widely used, in some places can replace the expensive diamond, common in grinding, grinding, drilling and other applications.
What is Boron Carbide B4C Used For?
Controlled nuclear fission
Boron carbide can absorb large amounts of neutrons without forming any radioactive isotopes, making it an ideal neutron absorber for nuclear power plants, where neutron absorbers control the rate of nuclear fission. Boron carbide is mainly used in nuclear reactors as a controllable rod, but is sometimes made into a powder to increase surface area.
At the Chernobyl nuclear accident in 1986, Russia finally stopped the chain reaction in the reactor after dropping nearly 2,000 tons of boron carbide and sand.
Boron carbide has been used as a coarse abrasive material for a long time. Because of its high melting point, it is not easy to cast into artifacts, but by melting the powder at high temperatures, it can be machined into simple shapes. Used for grinding, grinding, drilling and polishing of hard materials such as hard alloy and precious stone.
Boron carbide can also be used as a ceramic coating for warships and helicopters. It is lightweight and has the ability to resist armor-piercing bullets penetrating the hot-pressed coating as a whole.
It is used in the arms industry to make gun nozzles. Boron carbide, extremely hard and wear-resistant, does not react with acid and alkali, high/low temperature resistance, high pressure resistance, density ≥2.46g/cm3; Microhardness ≥ 3500kGF /mm2, bending strength ≥400MPa, melting point is 2450℃.
Because boron carbide nozzle has the characteristics of wear resistance and high hardness, boron carbide sandblasting nozzle will gradually replace the known carbide/tungsten steel and silicon carbide, silicon nitride, alumina, zirconia and other materials of the sandblasting nozzle.
Boron carbide is also used in the manufacture of metal borides and smelting of sodium boron, boron alloys and special welding.

As the duration of the conflict between Russia and Ukraine grows, its impact on commodities is widening amid the tug-of-war. Recently, European and American sanctions against Russia have been issued one after another. In response, Russia has taken advantage of its role as an important supplier of many energy and commodities, requiring exports of commodities, including energy, grain, metal, and wood, to "unfriendly" countries to be settled in robles. Therefore, it is expected that the price of the boron carbide powder will continue to increase.
