本文以硫酸钠为辅助剂,以钨酸钠为钨源,采用水热法制备了纳米三氧化钨粉末。采用FTIR、XRD、SEM等手段对纳米三氧化钨粉末进行了结构表征。结果表明,通过水热法合成的三氧化钨纳米颗粒为斜方晶系结构,纯度高,结构清晰,尺寸均匀。同时,对纳米三氧化钨材料未来的发展趋势进行了展望。
In this paper, sodium sulfate as an adjuvant, sodium tungstate as a tungsten source, the use of hydrothermal method to prepare nano-tungsten trioxide powder. The structure of the tungsten trioxide powder was characterized by FTIR, XRD and SEM. The results show that the tungsten trioxide nanoparticles synthesized by hydrothermal method are orthorhombic structure with high purity, clear structure and uniform size. At the same time, the prospect of the future development trend of nano-tungsten trioxide materials is prospected.
