CARBIDES - Hardness combined with corrosion resistance

The strength and wear resistance of carbide ceramics are impressive. The H.C. Starck portfolio includes ten carbidic ceramic precursors, including chromium carbide (Cr3C2), titanium carbide (TiC, TiCN) and  others. The most important carbidic ceramics we offer by far are materials based on silicon carbide (SiC) and boron carbide (B4C). They are produced using a variety of methods depending on the area of application.

Industrial to premium quality boron carbide

The tremendous hardness of boron carbide (B4C) is only exceeding by cubic boron nitride and diamond exceed. Boron carbide ceramics have mechanical properties similar to those of silicon carbide ceramics, but have even greater wear resistance and also offer outstanding chemical resistance to acids and bases. The combination of extremely low density (2.51 g/cm3), high mechanical strength and elastic parameters makes these ceramics particularly interesting for protective ballistic applications in defense technology. H.C. Starck provides boron carbide in industrial qualities (HD grades) with a wide particle grain distribution as well as in premium qualities (HP and HS grades) with an extremely narrow particle grain distribution.
