摘要
研究了一种金属钽粉的湿法提纯方法,即用钠还原后的原生钽粉粒子经水洗和混合酸酸洗,使钽粉中的O,C,Si及Fe,Ni,Cr等杂质质量分数明显降低,达到金属钽粉精炼提纯的目的.
A wet purification method of refining metal tantalum powder was researched.After sodium reduction,the primary tantalum powder particles was washed by water and by mixed acid,and other impurities content,such as oxygen,carbon,Si,Fe,Ni and Cr in tantalum powder,were reduced significantly,the target arrived.
