| 摘 要： | 首次采用高温快速合成方法成功地将比例适当的Sc2O3和WO3粉末合成了形貌良好的Sc2（WO4）3材料，并对该材料使用了多种手段进行分析。拉曼光谱分析说明在合适工艺参数下高温快速烧结可避免原料挥发，使原料完全参与反应。X射线衍射（XRD）分析表明合成物主要是Sc2（WO4）3材料，属空间群Pnca，具有正交结构，可以呈现负热膨胀特性。扫描电镜（SEM）发现合成物晶粒分散性好，呈链状并互相纠缠在一起。能量散射光谱（EDS）分析显示合成物内部成分分布均匀。

| Abstract: | Sc2(WO4)3 ceramic had been successfully and rapidly synthesized with a proper proportion of Sc2O3 and WO3 by high-heat and fast way for the first time. The microstructure observation, component and phases analysis of this ceramic were performed by a Raman spectrometer, scanning electron microscopy, energy-dispersive spectrometer and X-ray diffractometer. The Raman spectrum revealed that the volatility of WO3 can be avoided in the high-heat and fast synthesis and that the raw materials can react completely u... |
