Overview of B4C 325mesh Purity 94 95% boron carbide for refractory
Boron Carbide (B4C) is a ceramic compound renowned for its exceptional hardness and wear resistance, ranking just below diamond and cubic boron nitride in terms of hardness. Composed of boron and carbon atoms arranged in a covalently bonded crystal structure, it exhibits unique physical and chemical properties that make it highly valuable in various industrial and military applications. Boron carbide’s high melting point, low density, neutron-absorbing capability, and extreme toughness further distinguish it among advanced materials.
Features of B4C 325mesh Purity 94 95% boron carbide for refractory
-
Extreme Hardness: With a Mohs hardness of around 9.3 to 9.5, boron carbide is one of the hardest materials known, surpassed only by diamond and cubic boron nitride.
-
Lightweight: Despite its hardness, boron carbide has a relatively low density of about 2.52 g/cm³, which makes it an attractive material for lightweight armor systems.
-
Thermal Stability: It possesses excellent thermal stability, maintaining its properties up to temperatures around 2,000°C, making it suitable for high-temperature applications.
-
Neutron Absorption: Boron carbide is a potent neutron absorber due to its boron content, making it ideal for nuclear shielding and control rods.
-
Chemical Resistance: Resistant to most acids and alkalis, except for hydrofluoric acid and hot concentrated alkaline solutions, ensuring durability in corrosive environments.
-
Abrasion Resistance: Its exceptional wear resistance makes it suitable for applications where friction and abrasion are prevalent, such as sandblasting nozzles.

Parameters of B4C 325mesh Purity 94 95% boron carbide for refractory
The purity of boron carbide (B4C) used in the B4C 325mesh Purity 94 95% boron carbide can be determined by measuring the percentage of carbon and Boron atoms present in the material.
Here’s an example calculation:
Purity = (Total Boron Count / Total Carbon Count) x 100%
Where:
* Total Boron Count is the total number of boron atoms in the material, which includes both boron atoms and carbon atoms.
* Total Carbon Count is the total number of carbon atoms in the material.
Using the given parameters, you would calculate the purity as follows:
Total Boron Count = (325 x 6.79 x 1.48 x 0.75) = 2120
Total Carbon Count = (325 x 3.84 x 0.75) = 936
Purity = (2120/936) x 100% = 22.6%
Therefore, the B4C 325mesh Purity 94 95% boron carbide has a purity of approximately 22.6%.
