Abstract

The structure, phase composition and properties of hot-pressed mixtures based on boron carbide (B4C) and carbon nanotubes (CNT) were studied. Used boron carbide powder was produced by LLC PIChT and CNTs were made in Russia and Korea. Sintering was carried out in vacuum at 2100 °C and under the pressure of 30 MPa. The samples of ceramics have been obtained with the ballistic armour performance, which is ∼ 26% higher than that of ceramic samples without additives.
