Introduction of Boron Carbide Plate

Boron Carbide Plate is a high-performance ceramic plate made from boron carbide (B4C) material. Boron carbide is a super-hard material with high hardness, low density, and excellent wear, and corrosion resistance, and it is widely used in industrial, military, and nuclear energy applications. A boron carbide plate is usually made using a hot press sintering or cold press sintering process, with dense structure and excellent mechanical properties.

Features of Boron Carbide Plate

High hardness: The hardness of boron carbide is second only to diamond and cubic boron nitride, with Mohs hardness as high as 9.3, making it an ideal wear-resistant material.

Low density: With a density of approximately 2.52 g/cm³, it is lighter than most metals and ceramic materials, making it suitable for lightweight applications.

Excellent Wear Resistance: Boron carbide plates have extremely high wear resistance and are suitable for high-wear environments.

High-Temperature Resistance: With a melting point of up to 2450°C, it maintains stable mechanical properties at high temperatures.

Corrosion resistance: Excellent corrosion resistance to acids, alkalis, and most chemical reagents.

Neutron absorption capacity: Boron carbide has a high absorption cross-section for neutrons and is a commonly used neutron absorption material in nuclear reactors.

High rigidity: It has a high modulus of elasticity and can withstand large mechanical stress.

Question 2: What are the main advantages of a boron carbide plate?

Answer: The main advantages of a boron carbide plate include high hardness and wear resistance, low density for lightweight applications, high-temperature resistance with a melting point of up to 2,450°C, excellent corrosion resistance, and high neutron absorption capability for the nuclear industry.

QUESTION 3: What is the role of boron carbide plate in the nuclear industry?

Answer: The boron carbide plate is mainly used as a neutron absorption material in the nuclear industry. Due to its high neutron absorption cross-section, it is used in the manufacture of control rods and shielding materials for nuclear reactors to effectively control nuclear reactions and ensure safety.

Question 4: What is the manufacturing process of a boron carbide plate?

Answer: Boron carbide plates are typically manufactured through either a hot press sintering or a cold press sintering process. Hot press sintering is carried out at high temperatures and pressures to obtain high-density and strength plates, while cold press sintering is suitable for complex shapes through low-temperature molding and subsequent sintering treatments.
