Saturation of capillary pores in silicon carbide briqettes with liquid–phase carbon-containing solutions before the reaction-sintering

It has been studied the increasing of the carbon saturation of a porous silicon–carbide briquette by a multiple impregnation of oil coke solutions instead of a traditionally used lamp black hardphase powder or fine-dispersed graphite powder intended for a reaction sintering of silicon carbide aimed to decrease the free silicon part, which remains in the structure after sintering.
