美国橡树岭国家实验室、劳伦斯利弗莫尔国家实验室和Eck工业公司研制了一种超强含铈铝合金。美国稀土矿石中铈和镧含量最高,铈含量为一半多,因此美国是富铈国家,这种材料的研制成功和应用将使美国过量的稀土铈产生较大市场价值。如果1%的铝合金市场使用铈,那就意味着3 000 t铈用量。除了发挥铈的市场价值,新合金还具有重要的材料特性优势,即更高的热容限。
Oak Ridge National Laboratory, Lawrence Livermore National Laboratory and Eck Industrial Company developed a super-cerium-containing aluminum alloy. In the United States, the content of cerium and lanthanum in the rare earth ore is the highest, and the content of cerium is more than half. Therefore, the United States is a cerium-rich country. The successful development and application of this material will make the excess rare earth cerium in the United States have greater market value. If 1% of the aluminum market uses cerium, it means 3 000 t of cerium usage. In addition to exerting the market value of cerium, the new alloys also have important material property advantages, namely higher heat tolerances.
