Origin of Superhardness in Icosahedral B12 Materials. — Starting from a chemical
viewpoint, a simple method for evaluating hardness of boron-rich phases is given.
45- 012 bond
The method is applied to α-B12, B13C2, and B12X2 (X: O, P, As), and the predicted hardness values are in agreement with available experimental values. It is expected that boron-rich materials formed by adding some element to boron icosahedra have great potential as new superhard materials for industrial use. — (GAO*, F.; HOU, L.; HE, Y.;
