95% Boron carbide F40 F46 F54 grain from China
Boron Carbide powder 325mesh
neutron shielding additive B4C boron carbide powder，also known as B4C is produced from high temperature smelting boric acid and carbon materials in electric furnaces. Boron carbide is with high hardness up to Mohs’ 9.3, which is the third hard material besides Diamond and CBN.
Properties:
- High temperature resistance, acid-alkali resistance
- Boron carbide can get bigger Neutron interception area with high Neutron absorb ability.
- High strength, high chemical stability
- Low specific gravity
