Abstract
Paper deals with the low cost route of the preparation of SiC/Si3N4 nanocomposite. It is shown that SiC nanoinclusions distributed within the Si3N4 matrix can be produced by carbothermal reduction of fine SiO2 particles added into a starting mixture. The amount of SiC nanoinclusions can be adjusted by the appropriate amount of SiO2 + C additives. Almost full density of the final composite was achieved by hot-pressing at 1750 °C using a “special” heating regime allowing the outgasing of CO as a product of carbothermal reduction.
