Abstract

Several authors have described the formation of large voids in alkali halide crystals, i.e. large enough to be detected by ordinary light microscopy. The earliest experiments by Mollwo and Pohl concerned the formation of large gas bubbles through a chemical reaction with suitable dopants (e.g. by heating KCl crystals doped with CO3 −− in Cl2-atmosphere yielding CO2 and O2) (1, 2). The produced gas accumulated in spherical bubbles. The bubbles transformed into parallelepipedic voids, “negative crystals”, under prolonged thermal treatment. Most of the gas content of the initial bubbles had then been released into the lattice and had left the crystal by diffusion.
