摘要
利用循环还原-氧化工艺制备亚微米级的WO_3粉末,采用扫描电镜观察WO_3粉末形貌,用激光粒度分析仪分析其粒度分布。结果表明,通过控制反应温度和保温时间进行多次还原-氧化反应,能够获得亚微米WO_3粉末。
Submicron tungsten oxide powder was prepared by reduction-oxidation method. Scanning electron microscope was used to observe the powder morphology,and the particle size distribution was analyzed through laser particle size analyzer. The results show that submicron tungstic oxide powder can be obtained by controlling the reduction-oxidation temperature and holding time.
