Using hot explosive compacting technology and consolidating B 4 C powders in two stage at high temperatures enabled us to obtain compacts with high value of hardness and near theoretical density. This work contains results of calculations of B 4 C stress state under the shock loading that is being distributed evenly at a constant rate through the boundary retaining samples.

We synthesized star-shaped pentagonal microcrystals of boron carbide with an extremely low carbon content (~5%), from m-carborane under high pressure (7 GPa) and high temperature (1370–1670 K). These crystals have five-fold symmetry and grow in the shape of stars. A 5-fold symmetry in large micron-sized crystals is extremely rare making this a striking observation.
