Overview of 0.5 micron Cubic Boron Nitride
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 0.5 micron Cubic Boron Nitride
-
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 0.5 micron Cubic Boron Nitride
The 0.5 micron cubic boron nitride parameter refers to the average molecular weight of a cubic boron nitride (CBN) material, which is used in various applications such as high-performance memory devices, sensors, and catalysts.
The parameter typically ranges from 2.7 to 4.8 x 10^3 g/mol, depending on the specific properties of the CBN material. A lower value indicates higher purity and higher strength, while a higher value indicates lower quality and weaker performance.
It’s important to note that the parameter can be affected by factors such as crystal structure, particle size, and impurities, so it may vary depending on the particular CBN material being analyzed.
