Boron Carbide Plate, B4C Plate
Boron carbide plate, also known as B4C plate, is a ceramic material that consists of boron carbide and a small amount of carbon. It is one of the hardest materials known, with a Mohs hardness rating of 9.3, which is just below that of diamond. Boron carbide plates are commonly used in armor applications due to their high hardness and excellent ballistic performance.
Boron carbide plates are lightweight and have excellent strength and durability, making them suitable for use in various applications such as ballistic armor, wear-resistant coatings, and cutting tools. They are also resistant to high temperatures and are often used in nuclear applications and as neutron absorbers.
Boron carbide plates are typically fabricated using a hot-pressing method, which involves the application of high temperature and pressure to form a dense and uniform material. The resulting boron carbide plates have high density, high strength, and excellent hardness, making them suitable for use in extreme environments.

Boron Carbide Ceramic Applications
Boron carbide ceramics are applied widely in industries as wearing resistant materials, and abrasives. As an abrasive, it is used in powdered form in the lapping (fine abrading) of metal and ceramic products, though its low oxidation temperature of 400–500° C (750–930° F) makes it unable to withstand the heat of grinding hardened tool steels.
Because of its hardness, together with its very low density, it has found application as a reinforcing agent for aluminum in military armor and high-performance bicycles, and its wear resistance has caused it to be employed in sandblasting nozzles and pump seals.
Its ability to absorb neutrons without forming long-lived radionuclides makes it attractive as an absorbent for neutron radiation arising in nuclear power plants and from anti-personnel neutron bombs. Nuclear applications of boron carbide include shielding, control rod and shut down pellets. Within control rods, boron carbide is often powdered, to increase its surface area.
