Nano Boron Carbide (B4C) Powder Description
Nano Boron Carbide (B4C) (CAS: 12069-32-8) is a black crystal with a metallic luster, and its hardness is second only to diamond and higher than silicon carbide. The Mohs hardness is 9.3. The chemical properties are stable and do not react with acid-based solutions. The relative density is 2.52, the melting point is 2350℃, and the boiling point is higher than 3500℃. Molten boron carbide can dissolve a large amount of graphitic carbon. Boron carbide is stable in dilute acid solution and can be decomposed by mixed acid of sulfuric acid and hydrofluoric acid, mixed acid of sulfuric acid and nitric acid.
Boron carbide has a high capture ability for thermal neutrons, wear resistance, and semiconductor conductivity. In most cases, boron carbide (B4C) is used as the control material, it can meet the requirements of high-temperature reactors. Increasing the concentration of B10 elements in boron carbide can improve the control efficiency of boron material.
