    Abstract

    In order to investigate the mobility and structural change of barium and calcium compounds loaded on carbon substrate in the courses of heat treatment and of gasification, AES and EPMA were employed to observe the surface structure of amorphous carbon black impregnated by barium or calcium nitrate. The authors found that barium species migrated into the bulk of carbon in the course of heat treatment up to 1123 K, while calcium species did not. The difference in mobiity between barium and calcium species is due to the difference in the reducibility of these cations by the action of carbon in the course of heat treatment.
