Abstract
PURPOSE: To manufacture very econominally a high density carbon or graphite sintered body by holding a carbon powder primary burned molded body of relatively low density between a pair of anvils while leaving free space for bulging deformation around the anvils, followed by supply of current under press. and heating.
CONSTITUTION: Raw powder 4 consisting of carbon agregate powder and a binder is filled in mold 3, held between upper and lower punches 1, 2, and heated by supplying current while pressurizing P usually to 50W1000 kg/cm2 to burn and mold powder 4. The resulting primary burned molded body 14 of 60W90% density is held between upper and lower punch electrodes 11, 12 and heated by supplying current under compressive force about equal to or higher than that of the first process. At this time, body 14 is not contacted to the inside of frame body 13 to facilitate heating and pressure. By buckling and crushing body 14 the structure of body 14 is compacted at once to obtain a carbon or graphite sintered body the density of which is as high as 87W95% or higher.
