Abstract:

本文总结了不同形貌氟化镁的合成方法，包括溶胶凝胶法、微波合成法、二氧化硅模板法等。以酒石酸钠盐、乙二胺四乙酸二钠盐、柠檬酸钠盐为螯合剂，采用水热法成功制备了高度均匀的三维花状，且具有较高分散性的氟化镁微米颗粒。利用x射线衍射、扫描电子显微镜对材料进行了表征。同时调控溶液的PH值，以达到纯化氟化镁颗粒的效果。结果表明溶液的酸碱性对氟化镁的纯化起一定的作用。
This article summarizes the synthesis methods of magnesium fluoride with different morphologies, including sol-gel method, microwave synthesis method, and silica template method. Using sodium tartrate, ethylenediaminetetraacetic acid disodium salt, and sodium citrate as chelating agents, the hydrothermal method successfully prepared highly uniform three-dimensional flower-like and highly dispersible magnesium fluoride micron particles. The material was characterized by x-ray diffraction and scanning electron microscope. At the same time, the PH value of the solution is adjusted to achieve the effect of purifying magnesium fluoride particles. The results show that the acidity and basicity of the solution play a certain role in the purification of magnesium fluoride.
