Abstract

The critical dose for amorphisation, Dc, of two end-member zirconolites (CaZrTi2O7) with different stacking fault densities, was measured as a function of irradiation temperature from 20 K to 623 K using the HVEM-Tandem Facility at Argonne National Laboratory (ANL). Below 473 K, the Dc, values of both samples are identical within experimental error, showing only a small increase in Dc, from (2.5 to 4.6) × 1018 ions m−2 between 20 K and 473 K. At temperatures above 473 K, the data for the zirconolite containing many stacking faults is bracketed by two data sets from almost crystallographically perfect end-member zirconolites: one collected in this study and one collected in a previous study. The raw Dc versus temperature data from the zirconolites in this and a previous study suggest that the critical temperature above which samples cannot be amorphised and/or recrystallisation is complete, Tc, is between 600 and 1000 K. The data sets collected in this study are discussed in relation to a current model.
