稀土铝合金目前是一种应用较广,性能优良的金属材料,广泛应用于机械、化工、石油等行业。对于稀土合金中稀土总量的测定有部分报导,但大都甩比色法测定其低含量,而且允许共存的铝只是几至几十毫克,有的只适于作轻稀土,不适于作重稀土,有的甚至作标准都是用的铈,因此,对于Y—Al合金中常量稀土总量的测定目前还未见报道。笔者根据实际生产过程的需要,通过部分试验拟定了Y—Al合金中稀土总量的容量法测定。
Rare earth aluminum alloy is currently a wide range of applications, excellent performance of metal materials, widely used in machinery, chemicals, petroleum and other industries. Rare earth alloys for the determination of the total amount of some reports, but most of them by colorimetric determination of its low content, and allows the coexistence of aluminum is only a few to dozens of milligrams, and some only suitable for light rare earth, not suitable for heavy rare earth , And some even used as the standard cerium, therefore, for the Y-Al alloy constant rare earth total amount determination has not been reported. According to the actual needs of the production process, the author has developed a volumetric method for the determination of total rare earths in Y-Al alloys through partial tests.
