Fluorine is the most electronegative element and exhibits unique and outstanding oxidizing properties, which define a lot of its (possible) applications. However, very little is known about fluorine reactions at extreme temperature and pressure conditions (> 400 °C, > 400 bar up to approximately 4000 bar). This project is aimed towards the investigation of how fluorine and fluorine-based oxidizers, such as UF6 or ClF3, behave and react towards compounds or various elements at such high pressures and temperatures. The bold ideas to be tested include the capability of cesium to act as a p-element resulting in cesium oxidation states of more than +1; the formation of polyfluoride anions such as [F3]– and [F5]–, under these conditions; the synthesis of bulk compounds of Hg(IV), Cu(IV), Ag(V), Ir(VII), Os(VIII), Cr(VI); and more. As a side project, the chemistry of UF6, which is transported world-wide in special containers, will be tested against the durability of these container materials towards. Since the behavior of these construction materials towards UF6 in a fire (at temperatures above 400 °C) are completely unknown these interactions are worth investigating for academic andsafety reasons.

氟是电子元素最多的元素，并且具有独特而杰出的氧化特性，它定义了许多（可能的）应用。但是，对于在极端温度和压力条件下的氟反应（> 400°C，> 400 bar> 4000 bar）的氟反应知之甚少。该项目的目的是投资于在如此高的压力和温度下对化合物或各种元素的行为和反应。要测试的大胆想法包括剖宫产的能力，充当P元素，导致邻居氧化状态超过+1。在这些条件下，多氟化物阴离子（例如[F3]和[F5]）的形成； Hg（IV），Cu（IV），Ag（V），IR（VII），OS（VIII），CR（VI）的散装化合物的合成；还有更多。作为一个附带项目，将在全球范围内在特殊容器中运输的UF6的化学反应将根据这些容器材料朝向的耐用性进行测试。由于这些建筑材料在火灾中对UF6的行为（在400°C以上的温度下）完全未知，因此出于学术和安全原因，这些相互作用值得研究。
