摘要
本文采用机械球磨法制备纳米三氧化钨陶瓷粉末,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三氧化钨细粉;球磨时间和球料比以能够使颗粒尺寸趋于稳定的范围时为佳,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.The influence of ball milling parameters on size distribution of powder was studied systemically.The results show that rather pure WO3 nanometer powder could be prepared by mechanical ball milling.The time of ball milling and the weight ratio of powder to ball should be optimized according to the time for stabilization of powder size unreasonalle.Prolonging the time of ball milling and increasing the wtight ratio could not mill the powder f...
