Effect of explosion on matter. Shock compression topography of nitrates of the alkali metals
Penetration of 0.05–1.5% iron into the compressed material, the contamination being greater, the less densely packed the bomb is; contamination increases toward the bottom of the cylinder.
The density of the nitrates decreases and their dielectric constant increases. After remelting these properties return almost to the original state.
The compressed material acquires an alkaline reaction, which disappears on annealing only in the case of NaNO3.
The UV and IR spectra of the compressed nitrates reveal thermal and radiation effects, the latter being identical with those obtained when the nitrates are irradiated with X-rays.
These observations are explained on the assumption of charge transfer from the NO 3 − ion to the alkali metal cation at the moment of maximum dynamic compression.
