Overview of boron carbide powder for boron carbide plate B4C sand for refractory material
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 boron carbide powder for boron carbide plate B4C sand for refractory material
-
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 boron carbide powder for boron carbide plate B4C sand for refractory material
The given parameters suggest the use of boron carbide powder, which is typically mixed with boron carbide sand to create a product. The powder is usually prepared by combining boron carbide and boron carbide sand using a high-pressure extruder. The amount of powder needed can vary depending on the specific requirements of the project, but generally speaking, 0.5-1% of the total sand batch will be used to form the powder.
For example, if the project requires creating an overcoat of the powder onto a surface that has been sandblasted or honed, you may need to add up to 20-30% of the total sand batch for this purpose. However, it’s important to note that the specific ratio of the powder to sand batch required will depend on factors such as the size of the sandblasting/ Honing operation, the desired thickness of the powder layer, and the desired finish level.
It’s also worth noting that the types of powder available in the market differ, so the specific type of powder you choose may impact its effectiveness and performance in your project. Additionally, the type of equipment and techniques used for powder creation may also affect the results and ensure a consistent finish.
Overall, the given parameters suggest that a combination of boron carbide powder and boron carbide sand can be used to produce a professional-grade product for refractory materials. However, it’s essential to consider various factors before making any final decisions regarding the quantity and type of powder to be used.
