Abstract: In this paper, we employ SiC super hard ceramics that are widely used for the manufacture of individual means of protecting people from point impact effects and MgAl$_{2}$O$_{4}$ ceramics transparent in a wide spectral range that are used for protective screens of optical devices of aircraft, which are exposed to solid dust particles and atmospheric precipitation. Here, we study generation and relaxation of microcracks under impact action by using acoustic emission and electromagnetic emission, respectively. Since the mechanism of generation of these types of emissions has a different origin, then a comparison of the emission activity of one and another type allowed identifying general and individual patterns of impact damage to SiC and MgAl$_{2}$O$_{4}$ solid ceramics.
Keywords: impact destruction, silicon carbide, aluminum-magnesium spinel, acoustic emission, electromagnetic emission.
