【 摘 要 】

This paper discussed the microstructure and mechanical properties of ceramic tablets obtained from mixtures of boron carbide-based powders with various submicron additives. As the main powder for the study was used crystalline powder of boron carbide brand F400 (PJSC "Zaporizhia Abrasive Plant") with an average size of 20 microns. Submicron powders of boron carbide, boron nitride and carbon nanotubes were used as additives. It is shown that with the hot pressing parameters used, active sintering does not occur. Sintered tablets based on boron carbide F400 with additions of 10% by weight have the same hardness as tablets obtained from submicron powders. These additives could be perspective for further applications.
