Boron Carbide Properties
Product Performance of Boron Carbide Nanoparticles Nano B4C Powder CAS 12069-32-8:
Boron carbide nanoparticles Boron carbide has high purity, small particle size, uniform distribution, large SSA, high surface activity, and low bulk density. It is a synthetic super-hard material and one of the hardest artificial abrasives. Chemical properties, non-magnetic, high and low temperature resistance, strong acid and alkali resistance. The hardness is only less than diamond. As an abrasive, it has extremely high grinding efficiency and is an ideal substitute for diamond.
In addition, boron carbide can effectively absorb neutrons without emitting gamma rays harmful to the human body, and it will not form secondary radiation pollution.

Application of Boron Carbide Nanoparticles Nano B4C Powder:
Boron Carbide nanoparticles is used in carbon-containing refractories to play an antioxidant role, which can make the product densify, 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 super-hard 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 diamond. Therefore, as a grinding medium, it can be suitable for almost all grinding situations except diamond.
Nano boron carbide ceramic sealing ring is widely used in pumps containing a large amount of solid particles due to its high hardness and high corrosion resistance. Its service life can reach more than one year. It is an ideal material for sealing where the requirements are extremely strict and no leakage.
