Conclusions
In considering possible mechanisms for formation of superhard materials, the most interesting appears to be partial fusion of the carbon or boron nitride with subsequent crystallization of diamond or the cubic boron nitride phase from the melt. The possibility of diamond synthesis from amorphous forms of carbon is evidence in favor of this hypothesis. However, interpretation of results is complex and ambiguous.
The new method of detonation synthesis of superhard materials is distinguished by simplicity, quite high efficiency of conversion of original material into end product (up to 50%), the possibility of accomplishing synthesis in explosion chambers, and the possibility of superhard material production using automation techniques.
