bastnaesite

1.A stepwise carbochlorination-chemical vapor transport(SC-CVT) technique is proposed for separation of thorium from mixed bastnaesite-monazite concentrate.

以氟碳-独居石混合稀土为研究对象,采用步选择性碳热氯化-化学气相传输反应(SC-CVT),实现钍与其它稀土元素的离。

2.Neodymium is a bright, silvery rare-earth metal element, found in monazite and bastnaesite and used for coloring glass and for doping some glass lasers.

1据查，钕是“一种亮银色的稀土金属元素，见单独在石和氟碳锑中存在，用璃染色和一些光器上色。
