利用白云鄂博矿资源废弃物中有价元素以共伴生形成存在的特点制备了高性能的矿渣纳米晶玻璃陶瓷。本文采用电感耦合等离子发射光谱（ICP）、X射线衍射（XRD）、拉曼光谱（Raman）、扫描电子显微镜（SEM ）等测试方法对样品的成分和结构进行了深入分析。ICP和XRD、SEM 实验结果表明，我们制备的玻璃陶瓷是主晶相为透辉石，晶粒尺寸在45～100nm范围含稀土元素的纳米晶玻璃陶瓷，SEM 面扫所显示的元素与ICP成分分析结果较为一致。Raman分析表明，其非晶相主要由具有不同非桥氧键的硅氧四面体结构单元构成的三维网络结构，进一步分析发现稀土微量元素对网络结构有十分明显的影响。我们把矿渣纳米晶玻璃陶瓷与相似成分的玻璃陶瓷的拉曼光谱对比，发现矿渣纳米晶玻璃陶瓷的拉曼谱带普遍比玻璃陶瓷对应的拉曼谱带波数低。相似成分的玻璃陶瓷与矿渣纳米晶玻璃陶瓷的成分差别主要是稀土元素等微量元素。本文的研究方法为研究玻璃陶瓷的成分与结构、性能之间的关系提供了一种研究思路。

The research group prepared the high‐performance slag nanocrystal glass ceramics by utilizing the valuable elements of the wastes in the Chinese Bayan Obo which are characterized by their symbiotic or associated existence .In this paper ,induc‐tively coupled plasma emission spectroscopy (ICP) ,X‐ray diffraction (XRD) ,Raman spectroscopy (Raman) and scanning elec‐tron microscopy (SEM ) are all used in the depth analysis for the composition and structure of the samples .The experiment re‐sults of ICP ,XRD and SEM showed that the principal crystalline phase of the slag nanocrystal glass ceramics containing rare earth elements is diopside ,its grain size ranges from 45 to 100 nm ,the elements showed in the SEM scan are basically in consist‐ent with the component analysis of ICP .Raman analysis indicated that its amorphous phase is a three‐dimensional network struc‐ture composed by the structural unit of silicon‐oxy tetrahedron with different non‐bridging oxygen bonds .According to the fur‐ther analysis ,we found that the rare earth microelement has significant effect on the network structure .Compared the nanocrys‐tal slag glass ceramic with the glass ceramics of similar ingredients ,we found that generally ,the Raman band wavenumber for the former is lower than the later .The composition difference between the glass ceramics and the slag nanocrystal with the simi‐lar ingredients mainly lies on the rare earth elements and other trace elements .Therefore ,we think that the rare earth elements and other trace elements remains in the slag nanocrystal glass ceramics have a significant effect on the network structure of amor‐phous phase .The research method of this study provides an approach for the relationship among the composition ,structure and performance of the glass ceramics .
