Boron Carbide (one of the three hardest material known) is inert and unaffected with hot hydrogen fluoride. Particle Size – -325mesh Purity: 99% Boron Carbide A4C Powder Boron carbide (chemical formula, B4C), a very tough, covalent, boron carbide and boron ceramic material is used in many industries, such as tank armor and bulletproof vests. Vickers hardness (which is 30 GPa) is one the hardest substances after diamonds and cubic boron nitride. Boron carbide (second only to cubic boron-nitride and diamond) is the most difficult known substance. Therefore, it’s called “black diamant”. Boron carbide is a hard material that has a very high hardness, approximately 9.5-7 on the Mohs scale. It can be used to absorb neutrons of high cross-section. This is to provide a shielding effect against neutrons. It can withstand most chemicals as well as radiation. Its Vickers toughness (38GPa), elastic module (460GPa), and fracture toughness (43.5MPam1/2) are all close to what the diamond has (1150 GPa / and 5.3MPam1/2). Boron carbide is a semiconductor, which has electronic properties that favor jump-type communication. The composition and order of the components determines the energy bandgap. Estimates of the bandgap are 2.09eV. There are several intermediate bandsgap states which can complicate the photoluminescence spectrum. The usual p type material. Boron carbonide was originally discovered by metal boride researchers in the 19thcentury. Scientifically, this compound was not known until the 1930s. Boron carbide can absorb lots of neutrons while not forming radioisotopes. Boron carbide is cheaper than diamond and cubicboron nutride. This makes it more common. Boron Carbide B4C Powder, which can replace diamonds, is often used in drilling, grinding and grinding.

Boron carbide B4C powder is obtained by mixing boron dioxide with carbon at high pressure in an electrical furnace. The carbothermic process usually employs boric acid or boreic anhydride for the raw material, and carbon as a reducing agent. A high-temperature reaction to reduce heat is performed in an electric oven furnace. Carbothermic reduction, with its simplicity and low cost, is the best method currently for industrial production. For preparing boron, carbide, you can use self-propagating, thermochemical or direct synthesis techniques, as well as sol-gel and mechanochemical approaches. Henri Moissan created Boron carbonide for the first times in 1899. Boron dioxide was made by reducing it with magnesium or carbon using an electricarc furnace. When carbon is involved, it occurs at a temperature greater than B4C. The result is large amounts carbon monoxide. 2 B2O3 + 7 C→B4C + 6 CO If magnesium is employed, the reaction can take place in a graphite “crucible” and can be removed with treatment using acid. Boron Carbide B4C powder Specifications:








Boron Carbide B4C Pulver: Boron carbide is known for being low in density, strong, stable at high temperatures, and good chemical resistance. Use ceramic reinforcement in materials that are wear resistant, such as light decoration, reactor neutron absorbers, and other similar products. Abrasive Materials It is widely used because of its superior grinding efficiency. Industrial Ceramic Materials Products made out of Boron carbide Powder: Sealing rings, sandblasting, and sandblasting products, bearings, propellers of mud pump, pestles, rocket launchers, ceramic coatings to warships, helicopters. It’s widely used for sandblasting, electronics and automotive. Material control for the nuclear industry Boron carbonide material features a significant thermal neutron trap section, high neutron absorbtion and radiation resistance. This material is widely recognized as both a shielding material and a control material for nuclear reactors. Bulletproof clothing You can use it in light-weight bulletproof armor to protect people, aircraft and ships. Increase mechanical component life For metal-based alloy powder, mix boron carbide and metal. These original parts can be treated to improve their wear resistance, as well as corrosion resistance to acid or alkali. Special absorber provides energy Boron carbide, commonly known as “black” gold,” is used as an energy source as well as solid fuel in rockets. Chemical industrial additives Boron carbide, due to its stability chemical properties, is not affected by acid and alkali solution and has a high chemical potency. Therefore, it is often used for production of other materials containing boron such as titanium boride, zirconium-boride, and titanium boride. Advanced ceramics Boron caride is an anti-oxidant material that is resistant to high temperatures and widely used in different fields of metalurgisty. Boron Carbide 3pdm particles (B4C),Boron Carbide 3pdm powder (B4C) Storage of Boron Carbide B4C powder B4C’s powder dispersion performance can be affected by damp reunion. B4C must be packed in vacuum and kept dry. B4C cannot be exposed to air. You should also avoid stressing the boron caride B4C dust.
