In the present study, alumina ceramics containing 99% and 99.8% alumina, which has been studied and indicated reliable performance in vivo and vitro experiments for another ideas before this study, were subjected to the high speed mechanical effects or ballistic performance of alumina by the way of terminal ballistic tests with armor piercing of 7.62 mm diameter was studied in order to reveal traumatological properties of the material. High values of ballistic efficiencies were obtained for thinner test material and for higher impact velocities. Results revealed the ballistic efficiency of ceramics considerably varies with the thickness and projectile velocity, for the velocities ranged from 576 to 803 m/s and thicknesses of 4.1 and 8.3 mm.
