Boron Carbide (B 4 C)

Boron carbide is one of the hardest known materials being only second to diamond. Its composition ranges from B 4.3 C to B 10.4 C. Technical boron carbide usually has a high carbon content and is labelled B 4 C, 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.
