Ultra fine B4C powder for high hardness and wear-resistant nano Boron carbide powder neutron absorption material directly supplied by Jiupeng

Hangzhou Jiupeng new material nanometer Boron carbide CY-B4C1, superfine Boron carbide powder is prepared by variable current laser ion beam vapor phase method, Boron carbide, alias Carbonado, Molecular formula is B4C, usually gray black micro powder. It is one of the three hardest materials known (the other two are diamond and cubic Boron nitride). Hard black glossy crystals. The hardness is lower than industrial diamond, but higher than silicon carbide. Compared to most pottery, its fragility is lower. It has a large thermal Neutron capture cross section. Strong chemical resistance. Not affected by heatHFAnd the erosion of nitric acid. Soluble in molten alkali, insoluble in water and acids. The product has high purity, small particle size, uniform distribution, large specific surface area, high surface activity, and low loose density. It is a synthetic superhard material with hardness only inferior to diamond, Mohs scale hardness of 9.46, microhardness of 5600-6200Kg/mm2, specific gravity of 2.52g/cm3, melting point of 2250 ℃. It does not react with acid and alkali solutions, and has advanced degree, 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 acid or alkaline aqueous solutions. It has stable physical and chemical properties and is suitable for grinding, grinding, drilling, etc. of hard materials.
