КЕРАМИЧЕСКИЙ НАНОСТРУКТУРИРОВАННЫЙ МАТЕРИАЛ НА ОСНОВЕ НИТРИДА КРЕМНИЯ И СПОСОБ ЕГО ПОЛУЧЕНИЯ
FIELD: chemistry.SUBSTANCE: invention relates to process for production of a nanostructured ceramic material based on silicon nitride SiN, modified by carbon. Material can be used for the manufacture of plates for bulletproof vests, as well as various components of products requiring increased hardness and crack resistance. High hardness and crack resistance is achieved by modifying the grain boundaries of silicon nitride with carbon. In this case, all of the carbon is distributed along the grain boundaries. Production method involves grinding silicon nitride with fullerene in a planetary mill to obtain an average particle size of 20 nm. This results in coating of nanograins SiNwith fullerene monolayer. Resulting silicon nitride nanopowder with fullerene is sintered at a pressure of 1-5 GPa at a temperature of 1100-1850°C.EFFECT: technical result of invention is to increase hardness and crack resistance of a ceramic material based on silicon nitride.2 cl, 3 dwg, 1 tbl, 5 ex
