This boron carbide (B4C) micron powder from Nanografi has a purity of 95+% and a nominal size of 250 µm, with an average particle size range of 180-270 µm. Boron carbide ranks among the hardest and most stable materials available, and it remains unaffected by acid and alkali solutions.
Its hardness makes the powder suitable as an abrasive for polishing and lapping, and as a loose abrasive in cutting work such as water jet cutting. The material has a melting point of 2350.0 °C and a boiling point of 3500.0 °C.
Boron carbide can also absorb neutrons without producing long-lived radiation, which is why it is used in nuclear shielding, control rods and shut down pellets. Elemental analysis gives a B : C ratio of 77-79 : 20-22, with B4C at 95% min, B2O3 at 0.5% max and Fe2O3 at 0.2% max.
- Abrasive for polishing and lapping of hard surfaces.
- Loose abrasive in cutting processes such as water jet cutting.
- Neutron shielding material in nuclear applications.
- Neutron-absorbing component in control rods and shut down pellets.
