Carbon materials were prepared by the spark plasma sintering (SPS) method with a short period, and without adding binders and additives. The purpose of this study is to examine the effects on several properties of carbon materials by SPS. The bulk density, shore hardness, shear strength and compressive strenght of carbon materials treated by SPS method were measured. In case of treatment temperature of 1800℃, and pressure of 60MPa, these valuse were the highest observed in this study. Microstructure of carbon materials were examined by scanning electron microscope (SEM). Results of cross section observation by SEM, number and size of pore of carbon meterials treated by SPS method were decreased with increasing treatment temperature and pressure. Crystal structure of carbon materials were analyzed by X-ray diffractometry.
