LiF-YF_3熔盐萃取提纯金属钇的研究

Study of Purification of Yttrium Metal by Method of LiF-YF_3 Fused-salt Extraction

采用氟化锂-氟化钇二元萃取剂熔盐萃取金属钇,既有效降低金属钇中的氧和钙含量,又减少了氟根含量,制备的金属钇纯度达99.35%(质量分数),有效地提高了金属钇的纯度,为工业化生产提纯金属钇开辟了新途径。

LiF-YF3 extraction agent used to extract yttrium metal not only effectively reduced oxygen content and calcium content in yttrium metal,but also reduced content of fluorinion in yttrium metal.Results show that purityof yttrium reaches 99.35wt%,the purity of the metal yttrium is effectively improved.
