球磨时间对固相法制备ZrW_2O_8的影响

Effect of Ball Milling Time on Synthesis of ZrW_2O_8 through Solid Reaction Method

目前,ZrW_2O_8的制备方法主要有固相反应法和湿化学法。以ZrO_2和WO_3为原料,采用固相法制备了ZrW2O_8。结果表明,ZrW_2O_8的含量随球磨时间的增加而减小,且球磨时间越长,烧结样品中越容易出现γ-ZrW_2O_8(正交相)。

At present, ZrW2O8 is generally synthesized by solid reaction method or wei-chemical process. ZrW20s has been synthesized through solid reaction method using ZrO2 and WO3 as the raw materials. The results reveal that as the ball milling time increases, the ZrW2O8 content reduces , and γ-ZrW2O8 is easier to obtain in the sintered sample.
