Description
Product Overview
The Boron Carbide Ceramic Sheet offered by SINM is engineered to meet the demanding requirements of modern industrial and scientific environments. Measuring precisely 50x50x4mm, this sheet is fabricated from high‑purity tetraboron carbide (B₄C), a material renowned for its exceptional hardness, low density, and unique neutron absorption properties. With a Mohs hardness of 9.36 and a microhardness range of 5400‑6300 kgf/mm², the sheet provides unparalleled wear resistance while maintaining a lightweight profile of just 2.59 g/cm³. Its melting point of 2450 °C ensures stability under extreme thermal conditions, making it suitable for high‑temperature processes such as sintering, casting, and thermal shielding. The sheet’s semiconductor‑like electrical characteristics enable specialized applications in electronics, while its chemical inertness guarantees resistance to strong acids and alkalis, eliminating concerns about corrosion or degradation during aggressive chemical handling. Designed for precision engineering, the sheet can be machined, laser‑cut, or shaped to exact dimensions without compromising structural integrity, offering flexibility for custom tooling, nozzles, and mechanical seals. Overall, the product combines the best of hardness, thermal stability, and chemical resilience, delivering a versatile solution for a broad spectrum of high‑performance applications.

Usage
Industries that demand superior material performance find the Boron Carbide Ceramic Sheet indispensable. In aerospace, the sheet is employed for thermal protection components, high‑temperature structural inserts, and neutron shielding in spacecraft, where weight savings and radiation resistance are critical. Electronics manufacturers integrate the material into semiconductor substrates, high‑frequency resonators, and protective casings for devices that operate under intense thermal and radiation stress. Chemical processing plants benefit from the sheet’s resistance to corrosive environments, using it for reactor linings, valve seats, and seals that must endure strong acids, bases, and aggressive solvents without degradation. Automotive and aerospace engineering teams also leverage the sheet for wear‑resistant bearings, high‑speed turbine components, and precision machining tools that require durability under high‑load conditions. Additionally, research laboratories and nuclear facilities employ the sheet for neutron capture experiments, leveraging its large thermal neutron cross‑section to enhance safety and measurement accuracy. The product’s compact size and uniform thickness allow for easy integration into existing systems, while its ability to be custom‑shaped ensures compatibility with a wide range of equipment and designs.

FAQ
What is the typical thickness tolerance for the sheet?
The sheet is manufactured with a thickness tolerance of ±0.02 mm, ensuring consistent performance across all dimensions and allowing precise integration into tight‑tolerance assemblies.
Can the sheet be machined or laser‑cut to custom shapes?
Yes, the Boron Carbide Ceramic Sheet can be safely machined, laser‑cut, or water‑jet cut using standard industrial equipment. We recommend using diamond‑coated tools and appropriate cooling to preserve surface integrity and avoid micro‑cracking.
Is the material suitable for high‑temperature applications?
Absolutely. With a melting point of 2450 °C, the sheet retains its mechanical properties at temperatures far exceeding typical industrial processes, making it ideal for furnace linings, thermal shields, and high‑heat exchangers.
How does the neutron absorption property benefit my project?
Boron carbide’s large thermal neutron capture cross‑section allows the sheet to act as an effective neutron shield, reducing radiation exposure in nuclear reactors, medical imaging facilities, and research laboratories, thereby enhancing safety and compliance with radiation protection standards.
