Boron carbide (B4C) bulletproof ceramic is the lightest and best bulletproof ceramic material in the world. Compared with other bulletproof ceramics such as silicon carbide (SiC), titanium boride (TiB2), alumina (Al2O3), silicon nitride (SiN), aluminum nitride (AlN), boron carbide (B4C) bulletproof ceramics occupy obvious advantages in density, Vickers hardness, Young's modulus and other aspects, and the comprehensive performance is better.
The properties of the world's main bulletproof ceramic materials are compared
Bulletproof armor ceramic type | density/g/cm3 | Vickers hardness/GPa | Young's modulus/GPa |
Atmospheric pressure silicon carbide（SiC） | 3.10-3.20 | 22-23 | 400-420 |
Aluminium oxide（Al2O3） | 3.60-3.95 | 12-18 | 300-450 |
Alumina - Zirconia（Al2O3-ZrO2） | 4.05-4.40 | 15-20 | 300-400 |
Hot pressed silicon nitride（SiN） | 3.20-3.45 | 16-19 | --- |
Hot pressed titanium boride（TiB2） | 4.48-4.51 | 22-25 | 550 |
Hot pressed aluminum nitride（AlN） | 3.20-3.26 | 12 | 280-330 |
The company can provide various types of boron carbide ceramic bulletproof parts according to customer needs, which are widely used in individual human protection and light and heavy armored vehicles, armed ships, armed helicopters protection.
