Experiments on explosive compaction of an oxide powder layer in a cylindrical container by sliding detonation of ammonite are performed with various thicknesses of the HE and the container and for various materials of the container and the powder. With increase in the loading rate, stepped irregularities appeared and increased in amplitude on the boundaries between the metal and the compacted ceramic layer. The ceramics layer in this case cracked into pieces, which were shifted relative to each other and pressed into the metal surface. The results obtained are explained by features of the compaction of the powder in the container by sliding loading. The strength of the ceramics turned out to be higher than that of the metal of the container, and the ceramics that formed immediately behind the incident shock wave in the powder experienced additional strain.
