Boron carbide (B 4 C) is the third hardest industrial material (after diamond and cubic boron nitride) and is used for components needing very high wear performance. Ceramic-based composites Ceramics are used as the reinforcement of composite systems such as GRP (glass reinforced plastics) and metal matrix composites such as alumina reinforced aluminium (Al/Al 2 O 3 ).

Boron carbide also contains sp 3-hybridized carbon, but these atoms serve as dopants within or linkages between B icosahedra (9, 10), rather than establishing the overall structural framework. Of broader interest are 3D covalent organic frameworks (COFs), which are formed by linking sp 2 -hybridized molecular building blocks, that have attracted attention for gas storage and separations ( 11 ).
