Consolidation of industrial silicon carbide powder was carried out using a spark plasma sintering unit. It has been shown that preliminary mechanical activation is a promising method for introducing a high content of boron additives into silicon carbide. The effect of the amount of boron additive on sintering, microstructure and properties of ceramic material has been studied. The obtained ceramics based on silicon carbide with a mass content of 10 & # 37; boron with a density of 3.12 g / cm 3 , a hardness of 31.9 GPa and a fracture toughness factor of 5.65 MPa • m 1/2 , promising for use as a structural material in nuclear reactors and gas turbine engines
