Imperfections in Metastable Crystals and their Relation to Stability.

Abstract

In order to localize the decomposition sites in solid Ba, K and Na Azides i.e. whether the decomposition occurs (1) homogeneously through the solid or (2) at dislocation sites inside the crystal or (3) on the surface, X-ray diffraction, X-ray topography, electron diffraction, optical microscopy and gas emission studies were made. The results indicate that the decomposition in its very first stage occurs at or near the surface at a few individual sites. It is not known whether these sites coincide with the emergence of dislocations from the interior. However, the density of sites is much smaller than the density estimated from X-ray topography measurements.
