稀土应用已深入国民经济各个领域,稀土产品越来越多走进百姓生活,但对大多数人,甚至有些稀土圈内的人士对每个稀土也未必十分了解。为了宣传介绍稀土知识,本刊从2005年第1期开始连续刊登“稀土元素家族系列档案”,将陆续分别公布17种稀土元素每一个成员的“档案”资料,并配合专门文章详细论述其发现与应用发展,以供大家参考。由于稀土元素家族具有太多的化学共性,有关其化学性质不在该档案中列述。 Rare earth applications have been in-depth in all areas of the national economy, rare earth products more and more into the lives of ordinary people, but for most people, even some people in the rare earth circle for each rare earth may not be well aware. In order to promote the introduction of rare earth knowledge, we published a series of “Rare-Earth Element Family Files” successively from No. 1 in 2005, and will publish “Archive” information of each of 17 rare earth elements one after another, and discuss the findings in detail with special articles And application development, for your reference. Due to the chemistry of the REE family, which is too much chemistry, its chemistry is not listed in the file.
