摘要：

The behavior of disordered or turbostatic (BNt) and three-dimensional-ordered highly crystalline (BNord) graphite-like boron nitride is studied over the pressure range 5-9 GPa and the temperature range 500-2500 K. It is concluded that in the case of the original BNt the activation energy of this first conversion into cubic boron nitride (BNc) is less by a factor of four than when BNord is used. It is shown that in the case of the original BNt the formation of BNc begins from the intermediate (meso-graphite) structure.
