Boron Carbide Nanoparticles Nano B4C Powder CAS 12069-32-8

What are Boron Carbide Nanoparticles?

B4C was discovered in the 19th century as a by-product of metallic boride reactions. It was not until 1930 that this material was scientifically studied.

The molar weight of Boron Carbide Nanoparticles is 55.255 g/mol, whereas the density is 2.52 g/cm3. Its crystal structure is rhombohedral. It is prepared by reaction of boric acid with graphite at 2600 °C. It has a thin range of particle size distribution, a larger specific surface area, and good purity. The Specific Surface Area of Boron carbide Nanoparticles is greater than 42 m2/g.

Boron Carbide Nanoparticles, nanodots, or nanopowder are spherical high surface area particles. Nanoscale Boron Carbide Particles are typically 10 - 100 nanometers (nm) with a specific surface area (SSA) in the 10 - 75 m2/g range. Nano Boron Carbide Particles are also available in passivated, ultra-high purity, high purity, and coated and dispersed forms. They are also available as dispersion through the AE Nanofluid production group. Nanofluids are generally defined as suspended nanoparticles in solution using surfactant or surface charge technology. 

Boron carbide Nanoparticles do not react with alkali or acid solution. The compound is usually resistant to high temperatures and has anti-oxidation properties, high strength, hardness, crushing efficiency, elastic modulus, self-lubricating characteristics, and larger wear resistance. Boron carbide nanoparticles have a higher cross-section of thermal neutron capture, with good anti-radiation performance and excellent neutron absorption properties.

How are Boron Carbide Nanoparticles produced?

Boron powder and carbon materials are used as raw materials, and transition metal inorganic salts are added as catalysts to reduce the required reaction temperature. Heating in the furnace and controlling the sintering process and raw materials can obtain nano boron carbide particles with a narrow particle size distribution and uniform morphology.

The chemical equation of the reaction is B+C=B4C.

Application of Boron Carbide Nanoparticles Nano B4C Powder:

Boron Carbide nanoparticles are used in carbon-containing refractories to play an antioxidant role, which can make the product density, prevent the oxidation of carbon in carbon-containing refractories, reduce porosity, increase the strength at medium temperature, and reduce cracks.

Nano B4C powder is an artificially synthesized superhard material. As an abrasive, it has a very high grinding effect without introducing impurities. It is an ideal substitute for diamond abrasives.

Adding nano-B4C bulletproof armor, the bulletproof plate has high hardness and small specific gravity; the mechanical properties and anti-penetration ability are greatly improved, and the armor protection ability is more prominent.

The hardness of the grinding ball made of nano-B4C by isostatic pressing is second only to that of a diamond. Therefore, as a grinding medium, it can be suitable for almost all grinding situations except diamonds.

Nano boron carbide ceramic sealing ring is widely used in pumps containing many solid particles due to its high hardness and corrosion resistance. Its service life can reach more than one year. It is an ideal material for sealing with strict requirements and no leakage.

Refractory materials: B4C powder is used in carbon-containing refractories to have an anti-oxidation effect, which can densify the product, prevent the oxidation of carbon in carbon-containing refractories, reduce porosity, increase mid-temperature strength, and reduce cracks.

Nuclear industry: This product has a higher efficiency of neutron absorption than micron-grade powder, so it is widely used in the nuclear and national defense industries. Using B4C material as the isolation block makes the storage pool that can meet the storage period of 15 years and meets the requirement of the International Atomic Energy Agency's recommended temporary storage of spent fuel for at least 50 years of design life.

Military career: Add nano-B4C armor; the plate has high hardness and small specific gravity; the mechanical performance and anti-penetration ability are greatly improved, and the armor protection ability is more prominent.

High-precision nozzle: Because of its lightweight and high hardness, Nano B4C is widely used in producing hand-held sandblasting machine nozzles, hydraulic cutting nozzles, etc. B4C ceramic nozzle has the characteristics of long life and small size change.

Abrasives: Nano-B4C powder is a synthetic superhard material. As an abrasive, it has a very high abrasive effect and will not bring impurities. It is an ideal substitute for diamond abrasives.

Grinding media: Grinding balls prepared by isostatic pressing of nano-B4C, the hardness is second only to diamond, so as a grinding media, it can be suitable for almost all grinding occasions except diamond.

Sealing ring: A sealing ring made of nano-B4C ceramics, due to its high hardness and high corrosion resistance, is widely used in pumps containing many solid particles and liquids. Its service life can reach more than one year, and it is an ideal material for sealing in extremely strict and leak-free occasions.
