Boron carbide (chemical name B4C), is a covalent boron carbon material and extremely hard. It is usually gray-black in micro powder form and commonly used in tanks armor, bulletproof vests, and other industrial applications. Vickers hardness, which exceeds 30 GPa is one of three hardest known materials after diamond and cubic boron nitride. Boron carbide ranks third in the hardest substances, behind diamond and cubicboron nutride. It is therefore called “black diamond”.
Boron carbide (approximately 9.75 to 9.75 on Mohs hardness) is strong and extremely tough. This material is useful for absorbing neutrons and has an excellent shielding performance. Stability of most chemicals and radiation. Its Vickers hardness, elastic modulus and fracture toughness are very close to diamond’s (1385 GPa and 55.3 MPa*m1/2).
Boron carbide is an electronic semiconductor that has jump-type transmission. The order and composition determine how wide the energy bandgap. With multiple intermediate bandgaps states complicating the spectrum, the bandgap can be estimated at 2.09eV. The typical material type is p.
Boron carbide was first discovered as a side effect of the research into metal boride in the 19th Century. It was only scientifically explored until the 1930s.
Boron carbide absorbs a lot of neutrons but does not make radioisotopes. It is therefore a great neutron absorber for nuclear power stations. In comparison to cubic boron nutride and diamond, boron carbonide is simple to produce and inexpensive, making it more widespread. This can replace high-end diamonds at certain places. It is used extensively in drilling, grinding, and grinding. If you are interested in buying Boron Carbide B4C Powder, please send us an inquiry.

How does Boron Carbide Powder B4C Powder get made?
Boron Carbide Powder B4C Boron oxide is reduced with carbon using high heats in an electric furnace. The carbothermic method uses either boric acid (or boric anhydride) as the raw materials and carbon as the reducer. An electric arc furnace is used to perform the high temperature reduction reaction. Carbothermic reduction is still the most popular method to industrially produce boron carbide. It has simple reactions and low production costs. Additionally, self-propagating heat reduction methods, mechanochemical and direct synthesis methods are available for the preparation of boron caride.
Henri Moissan first synthesized Boron carbide back in 1899. The presence of carbon and magnesium allowed Boron Trioxide to be reduced in an electric furnace. For carbon, this reaction takes place at a higher temperature than B4C and results in large amounts of carbon monoxide being released.
2 B2O3 + 7C-B4C +6 CO
If magnesium is present, it can be used in graphite crucibles. After the reaction, acid treatment can remove the magnesium byproduct.

Boron Carbide B4C powder:
Boron carbide has low density, great strength, high temperature stability and excellent chemical stability. Wear-resistant materials include ceramic reinforcement phases, particularly in light decoration, and reactor neutron absorbers.
High-quality and sophisticated abrasive material
Due to its excellent grinding performance, boron carbide is used primarily in grinding of materials. This includes: Grinding, drilling, polishing and grinding of hard materials (e.g. gems, ceramics or knives), bearings, cemented carbides and bearings.
Industries ceramic materials
Boron carbide powder products include sealing rings and sandblasting tools, bearings, seals rings, nozzles, bearings. Plungers of mud pumps. Pestles and rocket launchers. Ceramic coatings to warships. The material has high melting points, high hardness and high elastic modulus. It is also highly versatile and used widely in electronics, aviation, information and other sectors.
Materials for control and protection in the nuclear industry
Boron carbide material is highly recommended because of its high thermal neutron capture and neutron absorption. It can also be used as an international shielding material or nuclear reactor control material.
Bulletproof armor
Because of its strength and low specific gravity it’s ideal for light bulletproof armor. It can protect aircraft, boats, and even human beings.
Enhance the mechanical part’s life
Combining boron-carbide powder and metal will produce a metal-based alloy powder. This material has been treated with special surfaces to make the original mechanical parts more resistant to wear, corrosion and acid/alkali resistance.
Special absorber provides energy
Boron carbide (also known as “black Gold”) is used to provide power in the form of a powdered fuel or solid fuel for rockets.
Chemical industry additives
Because of its chemical stability, boron caride doesn’t react with acids and alkali solutions. Also, it has a high potential for chemical reaction, making it a popular material in other boron-containing materials like titanium boride or zirconium borid.
High-quality refractories
Boron carbide’s anti-oxidation properties and resistance to high temperature are reasons why it is widely used as a high quality refractory material in many fields of metalurgisty such as steel stoves or kiln furniture.
Boron Carbide powder storage conditions:
B4C powder dispersion performance will be affected and the use of B4C should not be compromised by damp reunion. Boron carbide B4C Powder must be kept dry and in vacuum packed. Additionally, boron carbonide B4C powder must be kept away from stress.
Shipping and Packing of Boron Carbide Powder B4C powder
There are many options for packing, which depend on the amount of boron carbonide B4C powder.
Boron carbide B4C powder packing – vacuum packing, 100g to 500g or 1kg/bag at 25kg/barrel. Or as you request.
Boron carbide B4C Powder shipping: can be shipped by sea or by air?within 24 hours of receipt.
