引言

離子型稀土礦是我國(guó)特有的優(yōu)勢(shì)礦產(chǎn)，離子型稀土資源富含中、重稀土元素，是技術(shù)產(chǎn)業(yè)發(fā)展中不

可或缺的戰(zhàn)略資源，是發(fā)光材料、高性能磁性材料、激光材料、磁致冷材料、光導(dǎo)纖維、陶瓷材料、磁

致伸縮材料的重要成分。我國(guó)開發(fā)離子型稀土資源已有五十余年的歷史，離子型稀土的生產(chǎn)和應(yīng)用發(fā)展

迅速，從礦山提取、冶煉到應(yīng)用形成了較完整的工業(yè)生產(chǎn)體系。GB/T18882旨在通過實(shí)驗(yàn)研究建立一

套完整、切實(shí)可行且適應(yīng)于離子型稀土礦混合稀土氧化物產(chǎn)品生產(chǎn)和貿(mào)易需求的化學(xué)成分分析的方法標(biāo)

準(zhǔn)。限于文件篇幅、使用需求、適用范圍以及各分析方法之間的技術(shù)獨(dú)立性等方面原因，GB/T18882

《離子型稀土礦混合稀土氧化物化學(xué)分析方法》擬由4個(gè)部分構(gòu)成。

—第1部分：十五個(gè)稀土元素氧化物配分量的測(cè)定。目的在于建立X射線熒光光譜法和電感耦合等

離子體發(fā)射光譜法測(cè)定離子型稀土礦中十五個(gè)稀土元素氧化物配分量的方法。

—第2部分：三氧化二鋁量的測(cè)定。目的在于建立電感耦合等離子體發(fā)射光譜法和滴定法測(cè)定離

子型稀土礦中三氧化二鋁量的方法。

—第3部分：二氧化硅含量的測(cè)定。目的在于建立分光光度法和重量法測(cè)定離子型稀土礦中二氧

化硅量的方法。

—第4部分：三氧化二鐵含量的測(cè)定

電感耦合等離子體發(fā)射光譜法。目的在于建立電感耦合等離

子體發(fā)射光譜法測(cè)定離子型稀土礦中三氧化二鐵含量的方法。

上述各個(gè)部分文件通過明確適用范圍、規(guī)范試劑、材料、試驗(yàn)設(shè)備和步驟，并經(jīng)多家實(shí)驗(yàn)室反復(fù)試

驗(yàn)和驗(yàn)證給出精密度數(shù)據(jù)，為離子型稀土礦品質(zhì)核查建立嚴(yán)謹(jǐn)、規(guī)范的標(biāo)準(zhǔn)化工作基礎(chǔ)。

離子型稀土礦作為生產(chǎn)氯化稀土和氧化稀土的最重要的原材料之一，其質(zhì)量影響著后端稀土萃取分

離效果及氧化物的品質(zhì)。鐵是離子型稀土礦中最常見的雜質(zhì)元素之一，現(xiàn)行大多數(shù)稀土產(chǎn)品的國(guó)家標(biāo)準(zhǔn)

都對(duì)鐵有控制要求。鐵雜質(zhì)元素不僅影響稀土產(chǎn)品的質(zhì)量，也制約著稀土產(chǎn)品的應(yīng)用范圍。鑒于此，增

加第4部分。本文件采用電感耦合等離子體發(fā)射光譜法，建立了規(guī)范、易操作、準(zhǔn)確度高的檢測(cè)

標(biāo)準(zhǔn)。
