Abstract Scope |
Analysis of related Ln2TiO5 compounds coupled with crystal structure detail in this study provides systematic and comprehensive ion-irradiation experimental data allowing trends and fundamental theories to be developed.
In situ ion-irradiation coupled with transmission electron microscopy (TEM) and electron diffraction are used for radiation damage response observation to simulate the damage effects of high-energy particles such as those from alpha-decay. Of particular focus, SADPs were used to determine the critical fluence of irradiating ions required for the transition from crystalline to amorphous allowing radiation response of the various ceramics to be compared. The critical fluence was also determined at a variety of temperatures allowing a critical temperature for maintaining crystallinity to be quantified. By defining the effect of crystal chemistry on ion-irradiation response complex ceramic compounds can be tailored to give the best possible properties for application. This is a first step in the process of validation for nuclear-based applications. |
