| 摘 要： | 以表面活性剂十六烷基三甲基溴化铵为辅助剂,用超声法制备纳米氧化钨粉体,采用XRD、TEM对粉体进行表征。研究结果表明,利用钨酸钠与盐酸反应可以得到钨酸纳米粒子,粒子的尺寸在70~100 nm之间。500℃煅烧3 h后产物氧化钨粉体的粒径在50~80 nm之间。初步探讨了WO3纳米粒子的形成机理。

| Abstract: | Nano-scale tungsten oxide powder was prepared by ultrasonic method via assembly of CTAB-assisted.The obtained powder was characterized by XRD,SEM and TEM.The results show that tungsten acid nano-particles can be made by acidification of sodium tungstate with the average diameter of the nano-particles about 70~120 nm.The average diameter of WO3 nano-spheres was about 50~80 nm after 30 minutes of calcination time at 500 ℃ The formation mechanism of the WO3 nano-spheres was also investigated. |
