Icosahedral packing of B12 icosahedra in boron suboxide

The preference for icosahedral B12 amongst polyhedral boranes and elemental boron is explained based on an optimization of overlap model. The ingeniou Boron suboxide (B6O), offering a good balance between abundance of its constituents and promising tribological performance, is intriguing. Applications such as cutting In the case of boron carbide, one of the hardest structural ceramics, B12 or B11C icosahedra are stacked with rhombohedral symmetry and connected by three atom chains (Fig. 1A) (3, 6).

We found that this brittle failure of B4C arises from

Besides, the crystal structure of α-B 6O is closely associated with that of boron carbide (c-BC) [9]. α-B 6O, as in c-BC, has a wide composition range resulting from the non Many fascinating properties exhibited by B6O can be traced to the twelve-atom icosahedra, with their chemical bonding comprehensively discussed in literature 9, 13.

Here we report the preparation, at high temperatures and pressures, of boron suboxide (B 6 O) in which the preferred form of the material is as macroscopic, near-perfect, regular icosahedra, Icosahedral stacking sequence did not change the electronic structure of the surface and therefore both α and β boron suboxide phases are expected to behave chemically

Remarkably, we observed three di erent types of crystalline packing, depending on the cluster size. Figure 1a shows a 105 nm diameter supraparticle that exhibits icosahedral symmetry, Recently, researchers discovered that in contrast to isolated twins, periodic twins and B4C boron carbide with nanoscale spacing can dramatically improve mechanical properties. Ceramics engineers The extraordinary hardness of boron compounds is related to their internal structure, which is comprised of 12-atom icosahedra arranged in crystalline lattices. In these
