The SEM image of the starting T-SiC powder is shown
in Fig. 1. The powder shows very fine particle size,
typical of powder synthesized by plasma technique. In
addition, particles show rounded morphology with a
very low level of agglomeration which is not usual for
powder with average particle size of 345 nm as T-SiC
(Fig. 2).
Density, shrinkage, and weight loss after sintering for
both T-SiC and C-SiC samples are reported in Table 2
(T.D. = 3.24 g/cm3). As it can be seen, sintered density
of T-SiC powder is identical to that of the commercial
SiC powder. The higher shrinkage obtained for T-SiC is
essentially due to the lower green density. Furthermore,
