常用于测定稀有金属及合金中氧的真空熔融等方法,操作繁杂、费时。我们本着“自力更生”、“洋为中用”的原则参考了资料的工作,将试样置于小型坩埚中,在碳饱和的铁锡浴中,采用氩气熔融 Commonly used in the determination of rare metals and alloys in the vacuum melting of oxygen and other methods, complicated operation, time-consuming. We have the spirit of “self-reliance,” “ocean for the use of” the principle of reference to the work of the material, the sample is placed in a small crucible, carbon-saturated iron-tin bath, the use of argon melting
