摘　　要：采用固体粉末法,制备成功钨酸锌晶须。用XRD,EDX和SEM方法研究了所得晶须的结构组成和形貌,并对晶须的形成机理及晶须生长的影响因素进行了研究。初步确定钨酸锌晶须的生长机理为VS机理,总结出晶须生长的影响因素有烧结温度,保温时间,成分比例和粉末尺寸。Zinc tungstate whiskers were prepared by solid state method. SEM was used to examine the morphology and microstructure of the whiskers. XRD and EDX were used to identify the phase composite. Whisker's growth mechanism and affecting factors were discussed. The experimental results show that the mechanism of zinc tungstate whiskers growth is vaporsolid process, the sintering temperature, holding time, ratio of components and fineness of powder are important process conditions of preparing zinc tungstate whisker.
