Product Details

High hardness 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.

Product Features:

1. High-temperature resistance, acid-alkali resistance

2. Boron carbide can get a bigger Neutron interception area with high Neutron absorbability.

3. High strength, high chemical stability

4. Low specific gravity
