Ceramic Materials Properties Charts

Typical Boron Carbide (B 4 C) Properties. 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.Ceramic composite of silicon carbide and aluminum nitrideDec 06, 1994 The ballistic performance of other high performance ceramics such as boron carbide (B4C) and plain SiC drops when the ceramics are impacted by projectiles at angles lower than 90° to the surface of ceramic. This performance drop is caused by the extensive fracture and consequential loss in shear properties of the more brittle ceramics.Ceramic-faced molded armor - PDF Free DownloadBoron carbide Boron carbide is among the hardest materials known to humans (Table 13.3). It has a very good performance/weight ratio, yet is also one of the most expensive. In contrast to Al2O3 and SiC, some B4C grades show lower efciency against tungsten-core ammunition.
