Abstract

The results of the study of structures and mechanical properties of ceramic materials which were obtained by hot pressing from the submicron AlB12C2 and AlB12 powder with and without the addition of TiC as well as from B4C without and with SiC additions are under the discussion. 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 and fracture toughness, light weight make the synthesized and sintered ceramics very promising as shock-wave resistant material.
