“…There are numerous observations of enhanced solid state reactivity in powders which have been subjected to shock compression and preserved for post-shock examination. Early work included reports of enhanced catalytic activity [1/2], enhanced sinterability [3], and formation of compounds in powder mixtures [4,5]. Recent, more quantitative, studies include observations of enhancement in catalytic activity in shock-modified rutile approaching five orders of magnitude [6,7], greatly enhanced solubility in shock-modified silicon nitride [8], reduction in reaction start temperature for shock-modified zirconia in reaction with lead oxide [9], and reduction in the monoclinic to tetragonal transformation temperature in zirconia [10].…”

Powders of AlN, TiC and TiB2 have been subjected to controlled shock loading with peak pressures in the samples between 14 to 27 GPa and preserved for post-shock study. Broadened x-ray diffraction peak profiles are analyzed by a simplified method and show increases in residual lattice strain and small decreases in crystallite size. Strain values range from 10−5 to 10−4 for TiB2 and to values larger than 10−3 for TiC and AlN.

The explosive compaction method consisting of a cylindrical container surrounded by a proper type and amount of explosive is an inexpensive method to achieve high densities close to theoretical density. The explosive's parameters have to be adjusted to the type of the powder to be compacted. The required explosive's pressure is linearly related to the Vickers hardness of the metal powder particles. If higher pressures are applied, an “explosive liquid phase sinter” ‐ process can be achieved, allowing the welding of individual particles. The residual properties of the material are characterized by a high defect structure and by dislocation densities and subgrain sizes comparable to those after heavy plastic deformation. The same is true of compacted ceramic powders. Enhanced sinter reactivity, chemical and catalytic reactivity may be the result of high values of stored energy observed in the ceramic materials, shock wave treated under conditions of explosive compaction. The properties of materials produced by shock‐wave synthesis or by shock‐wave transformation are also determined by a high‐density defect structure.
