In order to evaluate the abrasive resistance of coke oxidized with CO_2 gas, the rotational abrasive disk was used. The specimens of metallurgical and formed coke were oxidized unidirectionally with gas mixtures like bosh gases. The relation between the abrasive resistance and conversion ratio was studied. The results are summarized as follows : 1) The abrasive resistances of the bulk and matrix of coke can be evaluated distinctively by the indicies proposed in the present study. 2) The index proposed to show the abrasive resistance of the bulk coke against the abrasive wear has the linear relation with the conversion ratio. 3) The abrasive resistance of the bulk of coke decreases extensively with the increase in conversion ratio, while that of matrix does not decrease so much. Therefore, the degradation of coke can be attributed mainly to the decrease in the bulk resistance due to the enlargement of pore.
