Boron carbide micron F600 F800 for B4C ceramics

Boron carbide micron F600 F800 for B4C ceramics

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:

1. High temperature resistance, acid-alkali resistance
2. Boron carbide can get bigger Neutron interception area with high Neutron absorb ability.
3. High strength, high chemical stability
4. Low specific gravity
