Summary

In shock synthesis, a very short time duration of shock-induced high-pressure and high-temperature state is available and the initial form of a starting material plays an important role to control and promote chemical reactions. The shock conditions vary not only in pressure and temperature, but also in crystal orientation, stress and strain relation, and quenching rate. Taking various shock-induced transformations in BN as a model, we have discussed the effects of starting materials and shock conditions in order to understand the possible transformation mechanism. Both diffusional and diffusionless processes have been observed.
