Boron carbide (B 4 C) has higher hardness than alumina or silicon carbide. Its oxidation product (B 2 O 3 ) provides a protective skin at high temperatures (> 800 o C). Because of its high hardness and wear resistance, boron carbide is applied in low-temperature applications such as grinding wheel dressers, and abrasive blast or water jet nozzles.
Mar 09, 2014· Boron Carbide (B4C): The most expensive ceramic used in armor, and the second hardest material on Earth (behind diamond), it is also much lighter than Alumina. This material is used in the highest-end rifle plates, and can be enhanced with new methods (such as sinterless pressing) to achieve nearly 100% theoretical density (meaning there are no ...

Boron Carbide, or B4C, is an extremely hard ceramic material discovered in 1899. With a Mohs hardness between 9 and 10, boron carbide is one of the hardest synthetic substances known, being exceeded only by cubic boron nitride (cBN) and diamond. Besides, it has good chemical inertness and high neutron absorption cross section.
