| description | BackgroundCharacterizing the microstructure evolution of materials during the gas-solid reaction is crucial for the comprehensive understanding of the reaction mechanism. In situ synchrotron X-ray diffraction (XRD) is a powerful tool for this purpose. For the reactions involving corrosive gases, unique devices need to be designed for the in situ experiments.PurposeThe study aims to develop two kinds of in situ synchrotron XRD devices for characterizing gas-solid reaction.MethodsLiquid volatilization and solid heat treatment were applied respectively to the generation of reaction gas for two kinds of in situ synchrotron XRD devices. The gas-solid reaction in liquid volatilization was triggered and precisely controlled by injecting liquid into the cell, suitable for gas-solid reaction at room temperature and near atmospheric pressure. For in situ XRD characterization device with reaction gas generated by heat treatment of solid, both the cell and the X-ray window were made of quartz glass, hence suitable for the gas-solid reaction temperature up to 450 ℃ and X-ray photon energy above 18 keV.Results & ConclusionsThe two in situ devices have the advantages of compact, disassemble and reusable. These devices help to facilitate the application of synchrotron experimental techniques for in situ characterization of chemical reaction processes. |
