Although not household names , materials with names such as lanthanum , cerium and ytterbium can be found hard-disk drives , cellphones , electric-car batteries and other products .
尽管不是家喻户晓,但例如镧、铈、镱这些材料却可以在硬盘驱动器、手机、电动车电池及其他产品中找到。
Prices have soared : the cost of cerium oxide ( often used as a catalyst ) has increased sixfold since the start of the year , and is 20 times higher than in 2005 .
Lanthanum , for instance , still hovers 18 times above its 2009 price , while prices for cerium are still nearly 25 times higher , according to lynas .
据lynas的数据,镧元素价格目前是2009年的18倍,而铈价格仍比当时高出近25倍。
Instead of a rare-earth-free magnet , he 's making a " free rare-earth magnet " with cerium , one of the most abundant rare-earth elements in the world .
与无稀土磁铁不同,他将铈这种稀土含量中最多的元素融入“无稀土磁铁”中。
Cerium oxide , which is used in catalytic converters and plasma televisions , is now down to us $ 16 a kilo , from us $ 102 a kilo last year .
用于催化转换器和等离子电视的氧化铈,现在已经从去年的每公斤102美元降到每公斤16美元。
" There is nothing cost prohibitive in our set-up , " she said . " And there is plenty of cerium for this technology to make a major contribution to global gasoline supplies . "
Cerium , lanthanum , praseodymium , neodymium ... the mine described by the head of the denver-based molycorp minerals contains deposits featuring some of the more esoteric reaches of the periodic table .
铈、镧、镨、钕……他所讲的这个矿,其矿床富含周期表上某些比较神秘的元素。
Lenders have to judge whether cerium oxide , for example , will be closer to its three-year average of $ 1.83 per pound or its $ 16.33 per pound in september .
In an interview earlier this month , molycorp chief executive mark smith said he has seen signs of ' demand destruction ' for rare earths , as companies take steps to reduce their rare-earths use , such as glass makers recycling cerium .
