Discs of both T-SiC and C-SiC with diameter of
40 mm and thickness of 3 mm were prepared by
uniaxial pressing at 100 MPa followed by cold isostatic
pressing at 200 MPa. Sintering was performed in a
graphite resistance high temperature furnace in flowing
argon at 1 atm. Sintering for T-SiC was conducted at
1925 ℃ for 0.5 h, while for C-SiC was done at 1930 ℃
for 1 h. Both sintering processes were conducted
without sintering bed.
