The effects of three minor elements, S, Ce and Bi, on the inoculation ability and fading behavior of 1.0 wt%Ba-Fe-Si were investigated through thermal analysis. The performance of 1.0 wt%Ba-Fe-Si inoculant was better and more consistant at the high temperature range of 1,450- 1 ,500"C than that of low one of l,300~ 1 ,400“C. That was improved with individual addition of three minor elements. The optimum amount of addition was 1.0% of the weight of inoculant added, respectively. That was improved also by the simultaneous addition of two or three kinds of minor elements. Even though worse with the addition of two kinds of them simultaneously than with individual addition, that was improved with the simultaneous addition of all three kinds over that with the individual one.
