Boron Carbide (B4C)

Boron carbide is one of the hardest known materials being only second to diamond. Its composition ranges from B4.3C to B10.4C. Technical boron carbide usually has a high carbon content and is labelled B4C, for convenience. Due to its high hardness and Young’s modulus it is very resistant against abrasion and thus used in blast or spray nozzles and as an abrasive. These properties combined with its low density make B4C a superior material for light-weight ballistic armor.[SCH15]
