bastnaesite

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

以氟碳铈矿-独居石土矿为研究对象,采用步选择性碳热氯化-化传输反应(SC-CVT),实现钍与其它土元素的离。

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“一种亮银色的土金属元素，见于单独在石和氟碳锑矿中存在，用于给玻璃染色和给一些玻光器上色。
