摘要
采用机械球磨法制备纳米WO3陶瓷粉末,系统研究了球磨参数对粉末粒度的影响。结果表明,机械球磨法可以制取纯度较高的WO3细粉;球磨时间和球料比以颗粒尺寸趋于稳定的范围为佳,盲目延长时间、增大球料比起不到细化作用,相反会增加WC杂质的引入。
The nano-WO3 ceramic powder was prepared by mechanical ball milling method. And the influence of ball milling parameters on the size distribution of powder was systemically studied. The results show that the more pure WO3 nanometer powder can be prepared by mechanical ball milling technique. The time of ball milling and the ratio of ball to powder materials fit in the steaby particles＇ size. Prolonging the time of ball milling and augmenting the ratio of ball to powder materials are aimlessly idle to attenuate WO3; the other way round, it can increase the WC impurity in that case.
