抄録

Nitriding the high purity chromium prepared in our institute, we made the two kinds of chromium nitrides.<BR>We investigated their chemical procedures.<BR>Samples which were composed of nitrides and metallic chromium on the market were used.<BR>When the samples were dissolved in the perchloric acid (10%), chromium nitrides remained insoluble as the residue. This residue was filtrated and washed after dissolved with hydrochloric acid (6 N).<BR>The nitrogen of the β-Cr2N in the filtrate was determined with steam distillation process.<BR>After the residue was treated in the sulphuric acid, the potassium sulphate and the cupper sulfate, the nitrogen of α-CrN was determined with steam distillation process.
