Hot Pressed Boron Carbide
Composition
B4C
hot pressed boron carbide overview
Hot-pressed, also known as pressure assisted densified (PAD), boron carbide is one of the hardest materials available in commercial shapes. This exceptional hardness combined with low density is used in ballistic armor, maximizing protection while minimizing weight.
Example Applications
- Semiconductor heaters
- Substrates for LEDs and power electronics
