Boron carbide is the hardest material after diamond, giving it outstanding wear resistance. Its mechanical properties, especially its fracture toughness, are low, limiting its application. However, it is used extensively for ballistic armor and blast nozzles. Boron carbide is also a neutron absorber, making it a primary choice for control rods and other nuclear applications.*
