Abstract

1. A study was made of the effect of shock compression by waves of various intensities on aluminum and boron nitride powders. 2. It is shown that prior shock wave activation enables aluminum nitride parts with a relative density of up to 81% to be obtained without recourse to hot pressing. The densest sinterings, with a residual porosity of not more than 3%, are produced by sintering aluminum nitride compacts pressed by shock compression. 3. It has been established that shock compression of graphite-like boron nitride is accompanied by the formation of the wurtzite-like modification of boron nitride, as a result of which it is impossible to obtain high density in sintered parts.
