rare-earth metal

1 About 24 million tonnes of magnesium and 3.1 million tonnes of cobalt are estimated to be in manganese crusts grown on bedrock over millions of years, as well as 1.7 million tonnes of cerium, a rare earth element used in alloys.

2 Each successive rare earth element adds one more proton and one more electron.

3 Enlarge / About half of the world's rare earth element supply comes from this single mine.

4 Another challenge is that 40% of the critical materials used in an EV – a long list including everything from aluminum to yttrium, a rare earth element – must come from the U.S. or from nations that have a free trade agreement with the U.S.

5 As a first step, DOE recently announced plans for a first-of-its-kind national rare earth element facility that could look at how to transform untapped waste resources that contain valuable minerals.

6 Around 15% of the world’s rare earth element supply is sourced from Mountain Pass, according to MP Minerals.

7 And here China currently holds a monopoly on rare earth element (REE) extraction and processing to the tune of 90%.

8 Although indium is not technically a rare earth element, its economics are very much the same.

9 Uses: Forelectro - vacuum, lightening industry , rare earth metal smelting and glass melting, etc.

用途: 用于电真空 、 电光源 、 稀土冶炼及玻璃融化.

10 The oscillatory relaxation of the rare earth metal surfaces has been investigated with LEED spectra.

用LEED谱,研究了稀土金属表面的振动弛豫.

11 Yet another rare earth metal, lanthanum, is a major ingredient for hybrid car batteries.

而另一种稀土金属镧, 则是混合动力车电池的主要原料.

12 Summary The paper presents developments of synthesis , characterization, and applications of rare earth metal containing polymers.

本文综述了含稀土聚合物的合成 、 性质以及应用等方面的研究进展.

13 The color of Apatite is often due to the presence of rare earth elements.

磷灰石的颜色常取决于存在的稀土元素。

14 This method could determine many non-REE in enriched-europium mixture rare earth oxide at a time and it was a rapid method.

该方法能同时测定富铕混合稀土氧化物中多种非稀土元素的含量，提高了分析速度。
