By the heat treatments at 1700°-2000°C under 5 kbar, the sintered graphite disks were prepared from various starting materials, such as graphitizing polyvinylchloride coke, graphitized fine powder, non-graphitizing phenol resin char and carbon beads, fluid and gilsonite cokes with onion-like texture, and the powder of PAN fibre.<BR>From the polyvinylchloride coke and PAN fibre, the disks with high degrees of graphitization and orientation were obtained. The graphitized fine powders, phenol resin char, 1000°C-pre-heated carbon beads and fine powders of fluid coke gave the sintered disks with similar values of orientation degree, which being a little lower than that of the polyvinylchloride coke. The fluid coke and gilsonite coke gave relatively low degree of orientation. The 2000°C-pre-heated carbon beads gave the disks with high degree of graphitization, very low degree of orientation and high bulk density.
