    Abstract:

    The results of the study of structures and mechanical properties of ceramic materials will be discussed. These ceramic materials were obtained by hot pressing from the submicron AlB12C2 and AlB12 powder [1], with and without the addition of TiC, as well as from B4C, without and with SiC additions. Temperature, pressure and composition of the starting powder are optimized to obtain sintered bodies with desired high mechanical characteristics. X-ray diffraction, scanning electron microscopy and Raman microspectroscopy are utilized to investigate phase composition and microstructure of the sintered ceramics. High compression strength (1551 MPa for B4C, 1878 MPa for B4C-SiC-based material and 795 MPa for AlB12C2-TiB2 based material) together with high bending strength, hardness, fracture toughness, and a light weight make the synthesized and sintered ceramics very promising as a shock-wave resistant material. The effect of C, TiC and SiC additions on the properties of the resultant composites and the particularities of the ceramics destruction under shock loading will be discussed. The results of the modeling of ballistic characteristics will be discussed. The performed ballistic tests of 10 mm thick plates from the developed ceramic had a 2.63 g/cm3 density as well as a composition of 78 wt.% of B4C and 22 wt.% of SiC according to X-ray diffraction analysis. According to SEM microprobe X-ray analysis, stoichiometries B3.64CSi0.01 and SiC1.07, respectively, showed that the plates can withstand the shot of a B32 bullet with kinetic energy of 3.7 kJ from a 10 m distance.
