Abstract
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 further and might pollute the powder.
