Boron carbide (chemical formula approximately B4C) is an extremely hard boron-carbon ceramic and covalent material with many industrial applications. With a Vickers hardness of \"30 GPa, it is one of the hardest materials known, second only to cubic boron nitride and diamond.
Purity: 99%
CAS: 12069-32-8
The ability of boron carbide to absorb neutrons without forming long-lived radioactive nuclides makes it attractive as an absorber for neutron radiation generated by nuclear power plants and antipersonnel neutron bombs.
The nuclear applications of boron carbide include shielding, control rods, and particle closure. In control rods, boron carbide is usually powdered to increase its surface area.
Exceptional Hardness & Wear Resistance
Boron carbide is among the hardest known materials, enabling deposited films to deliver outstanding abrasion resistance and extended service life, especially in protective and tribological coatings.
Superior Chemical Stability
B₄C exhibits strong resistance to acids, alkalis, and oxidation, ensuring coatings maintain performance in corrosive and chemically aggressive environments.
High-Temperature Performance
With excellent thermal stability, boron carbide targets can operate reliably in high-temperature sputtering processes, producing coatings that remain stable under extreme conditions.
Uniform Sputtering & Film Quality
High-purity boron carbide targets provide stable sputtering rates and uniform erosion behavior, resulting in consistent, high-quality thin films required for precision applications.
Low Density with High Strength
The material offers a unique combination of lightweight structure and high mechanical strength, making it ideal for applications where both durability and weight reduction are critical.
