- 論文の詳細を見る
Determination of oxygen in metallic manganese, which is considered to be difficult by the conventional vacuum fusion method, was attempted by the argon-carrier fusion method. The gettering effect of manganese was found to be inhibited by useing a fresh bath, containing tin 15〜20 times the amount of sample, for each run and by carrying out the analysis at 1650±30℃. Analyses of several kinds of metallic manganese sample under these conditions gave well-reproducible results. Recovery of oxygen was determined to be 95〜110% by the addition of a definite amount of manganese oxide to these samples, showing that the gettering effect of manganese is inhibited completely.
