What is boron carbide powder?
Nano boron carbide and ultrafine boron carbide powder were prepared by variable current laser ion vapor phase method. Boron carbide, also known as black diamond, has a molecular formula of B4C and is usually a gray black micro powder. It is one of the three hardest materials known (the other two being diamond and cubic boron nitride). Hard black glossy crystal.
The hardness is lower than industrial diamond, but higher than silicon carbide. Compared to most pottery, it has lower fragility. Has a large thermal neutron capture cross-section. Strong chemical resistance. Not susceptible to corrosion by hydrogen fluoride and nitric acid. Dissolved in molten alkali but insoluble in water and acid.
What is the application of boron carbide powder
The product has high purity, small particle size, uniform distribution, large specific surface area, high surface activity, and low loose density. It is an artificially synthesized superhard material with a hardness second only to diamond, a Mohs hardness of 9.46, a microhardness of 5600-6200Kg/mm, a specific gravity of 2.52g/cm, a melting point of 2250C, and does not react with acid and alkali solutions. It has high degree of oxidation, neutron absorption, wear resistance, and semiconductor conductivity. It is one of the substances that is stable to acids, and is stable in concentrated or dilute acidic or alkaline aqueous solutions. Has stable physical and chemical properties, suitable for grinding, grinding, drilling, and other applications of hard materials.6. Refractory materials, fine engineering ceramics, such as high-precision nozzles, sealing rings, nuclear industry, and defense industry.
How to store this product
This product should be stored in a cool, dry room and avoid heavy pressure. Untreated powders should not be exposed to air during use to prevent moisture absorption and aggregation, which may affect dispersion performance and effectiveness.
