A closing synthesis device with special structure was designed to effectively collect the ZnO synthesized via self-propagating high temperature synthesis (SHS) method. With this device, the influence of CaF₂ on products was investigated. Products were characterized using scanning electron microscope (SEM) and X-ray diffraction (XRD). Results showed that with the increase of CaF₂, there is a trend of first increase and following decrease in the yield of products and there appears increasing amount of one-dimensional ZnO nanostructures and there are no obvious changes on the structure of products. Possible mechanisms of the influence of CaF₂ on products were discussed.

设计了一种具有特殊结构的封闭合成装置，以有效收集通过自蔓延高温合成（SHS）方法合成的ZnO。使用该装置，研究了CaF ₂对产品的影响。使用扫描电子显微镜（SEM）和X射线衍射（XRD）对产品进行表征。结果表明，随着CaF ₂含量的增加，产物的产量呈先增加后减少的趋势，一维ZnO纳米结构的数量增加，产物的结构无明显变化。讨论了CaF ₂影响产物的可能机制。
