The purity 99.99% of scandium oxide(Sc 2O 3) was prepared from tungstenic slag with extraction process. 用萃取法从钨矿渣制得纯度为99．99%25的氧化钪。

Then the new technology in preparation of high purity scandium metal was proposed and its purification mechanism w. 然后给出了用真空蒸馏法制备高纯金属钪的新工艺,并对其提纯机制作了探讨。

PMBPmediated emulsion liquid membrane Was developed to extract scandium from a mixture. 我们得到PMBP为载体的乳状液膜从混合液中提取钪。

The distribution in nature,application,and extraction technology of scandium are introduced. 论述了稀散元素钪在自然界中的分布、应用状况及提取技术。

This paper describes the acidity changes across the membrane when various carriers were used to extract scandium. 本文报导了使用不同载体萃取钪时,液膜内外相的酸度变化。
