Boron Carbide (B₄C) is one of the most valued members of today’s family of ballistic ceramics. It is extremely light, incredibly hard, and offers a high strength-to-weight ratio. It is commonly used as the strike face in armor systems to stop high-velocity kinetic projectiles. This article aims to provide an in-depth overview of this material—from its physical characteristics, working mechanisms, and applications to comparisons with other ceramics, its advantages and limitations, and procurement considerations.
