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,并利用多种分析手段对该材料进行分析.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.
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 -disoersive soectrometer and X- ray diffractometer.
