Abstract: Cubic silicon nitride was synthesized from a mixture of hexagonal silicon nitride and copper powder in a cylindrical recovery capsule. It was shown that the synthesis occurred only in the region of the Mach reflection of shock waves near the axis of the capsule. A method of loading the material with ejection of the sample from the capsule into an airtight container was developed. As a result of loading, up to 20% of the starting hexagonal silicon nitride transforms to the cubic phase.

Keywords: shock-wave synthesis, cubic silicon nitride.
