Boron Carbide:
Boron carbide (B4C chemical formula) is an ultra-hard boron carbide and covalent material. It can often be found in gray-black micro powders. 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 9.75 to 10.75 on the Mohshardness scale. It can be used to absorb neutrons of high cross-section. This is to provide a shielding effect against neutrons. Its stability to most chemicals as well as radiation. Its Vickers hardness of 38 GPa, elastic modulus of 460 GPa, and fracture toughness (43.5 MPam1/2) are all close to what the diamond has (1150 GPa & 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 2.09 eV. There are several intermediate bandsgap states which can complicate the photoluminescence spectrum. The typical material type is p.
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.

How do you make Boron Carbide B4C Pulver?
Boron carbide B4C powder is created by heating boron dioxide with carbon at high temperatures using an electric furnace. The carbothermic reduction process uses either boric acids or boricanhydride for the raw material, and carbon to reduce the amount. A high-temperature reaction to reduce heat is performed in an electric oven furnace. Presently, industrial production is dominated by the carbothermic process for boron caride. This has the advantage of being simple and cost-effective. For preparing boron, carbide, you can use self-propagating, thermochemical or direct synthesis techniques, as well as sol-gel and mechanochemical methods.
Henri Moissan created Boron carbonide for the first times in 1899. In the presence of carbon, or magnesium, bore trioxide can be reduced using carbon or magnesia in an electrical arc furnace. When carbon is involved, it occurs at a temperature greater than B4C. The result is large amounts carbon monoxide.

Boron Carbide for Powder (B4C):
Boron carbide is very strong, low in density, has high temperatures stability, good chemical stability, and has high strength. Use ceramic reinforcement in materials that are wear resistant, such as light decoration, reactor neutron absorbers, etc.
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, bearings. Also, the plungers of mud guns, rocket launchers and pestles. There are ceramic coatings that can be used on warships. It’s widely used for sandblasting, electronics, information and automobile.
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 and corrosion resistance against acid and alkali.
Special absorber provides energy
Boron carbide, commonly known as “black” gold,” is used in powder form as an engine fuel and solid rocket fuel.
Chemical industrial additives
Because of its stability chemical properties, Boron Carbide is not affected by acid and alkali solution and has a high chemical potency. Therefore, it is often used to make other boron containing materials such as titanium boride and zirconium-boride.
Advanced ceramics
Boron caride is widely utilized in different fields of metallurgy due to its high resistance to heat and anti-oxidation.
