Role of Carbon in the Sintering of Boron-Doped …

The effect of carbon on the sintering of boron-doped SiC was studied. The free carbon present in the green compact was found to react with the SiO 2 covering the surfaces of the SiC particles; however, even if no carbon was added, the surface SiO 2 reacted with the SiC itself at a slightly higher temperature. This latter reaction was associated
